Incorporation of conjugated polymers into porous metal oxide networks is a challenging task, which is being pursued via many different approaches. We have developed the guided in situ polymerization of poly(2-methoxy-5-(2′-ethylhexyloxy)-p-phenylenevinylene) (MEH-PPV) in porous titania films by means of surface functionalization. The controlled polymerization via the Gilch route was induced by an alkoxide base and by increasing the temperature The selected and specially designed surface-functionalizing linker mols. mimic the monomer or its activated form, resp. In this way, we drastically enhanced the amount of MEH-PPV incorporated into the porous titania phase compared to nonfunctionalized samples by a factor of 6. Addnl., photovoltaic measurements were performed. The devices show shunting or series resistance limitations, depending on the surface functionalization prior to in situ polymerization of MEH-PPV. We suggest that the reason for this behavior can be found in the orientation of the grown polymer chains with respect to the titania surface. Therefore, the geometry of the anchoring via the linker mols. is relevant for exploiting the full electronic potential of the conjugated polymer in the resulting hybrid composite. This observation will help to design future synthesis methods for new hybrid materials from conjugated polymers and n-type semiconductors to take full advantage of favorable electronic interactions between the two phases. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).SDS of cas: 146370-51-6

On May 8, 2008, Kubo, Masataka; Ito, Takahito; Shoyama, Masashi published a patent.Application of 146370-51-6 The title of the patent was Organic-inorganic hybrid phosphors, their preparation, and their use for white light-emitting materials and capsule-type endoscopes. And the patent contained the following:

The organic-inorganic hybrid phosphors, useful for white light-emitting materials and capsule-type endoscopes, contain 蟺-conjugated poly(arylenevinylenes) in granular silica and are prepared by sol-gel processing of 蟺-conjugated poly(arylenevinylenes) having phosphonium end groups and alkoxysilanes. Thus, reaction of 4-methoxyphenol and 1-bromo-2-ethylhexane gave 4-(2-ethylhexyloxy)anisole, which was converted into a dialdehyde derivative (A) and diphosphonium chloride derivative (B) via a bis(chloromethyl) derivative A and B were copolymerized in CHCl3 in the presence of NaOEt to give a 蟺-conjugated poly(arylenevinylene), which was stirred with Si(OEt)4 in aqueous EtOH solution containing 2-amino-2-hydroxymethyl-1,3-propanediol dodecylsulfate salt and NH4OH to give an organic-inorganic hybrid phosphor. A UV-emitting diode chip was potted with a mixture of the phosphor, other phosphors prepared in similar manners, and silicone resins (KER-2667A and KER-2667B) to give a white light-emitting diode showing a UV peak at 373 nm and a broad spectrum with wavelength range 400-700 nm. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Application of 146370-51-6

On January 18, 2000, Dellsperger, Simon; Dotz, Florian; Smith, Paul; Weder, Christoph published an article.Synthetic Route of 146370-51-6 The title of the article was Synthesis and optical properties of novel poly(p-phenyleneethynylene)s. And the article contained the following:

In order to explore the influence of chem. modifications on the photophys. properties of poly(p-phenyleneethynylene)s (PPEs), a series of PPE-copolymers was synthesized, employing Heck-type cross-coupling reactions. UV/Vis absorption and photoluminescence experiments clearly demonstrate that the design of PPE-copolymers which comprise conjugated segments of well-defined length and (aliphatic) spacers in a strictly alternating fashion allows to tune the bandgap to higher energies, and thus the absorption and emission maxima to shorter wavelengths. The derivatization of the PPE backbone with electron-withdrawing substituents, by contrast, is found to be significantly less effective and only leads to comparably small shifts in the absorption and emission spectra. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Synthetic Route of 146370-51-6

Mechanistic studies on the polymerization of α,α’-dibromo-2-methoxy-5-(2-ethylhexyloxy)xylene have been performed. Polymerizations were initially carried out by adding potassium tert-butoxide to monomer in the presence of a chain transfer agent, anthracene. Anthracene showed little effect on the mol. weight of the resulting polymer, suggesting that the major polymerization route was not radically initiated. Polymerizations were also carried out by adding monomer to potassium tert-butoxide in presence of a nucleophile, 4-methoxyphenol. The mol. weight of the resulting polymer scaled linearly with the amount of 4-methoxyphenol, suggesting an anionic mechanism. In addition, each polymerization was monitored by in-situ torque measurements to further elucidate the polymerization mechanism and optimize polymerization conditions.

On September 1, 2000, Park, Lee Soon; Han, Yoon Soo; Hwang, Jin Sang; Kim, Sang Dae published an article.Application of 146370-51-6 The title of the article was Synthesis of conjugated polymers containing anthracene moiety and their electro-optical properties. And the article contained the following:

Both fully conjugated polymer poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene vinylene-alt-9,10-anthrylene vinylene] [poly(MEHPV-AV)] and conjugated/non-conjugated block copolymers poly(alkanedioxy-2-methoxy-1,4-phenylene-1,2-ethenylene-9,10-anthrylene-1,2-ethenylene-3-methoxy-1,4-phenylene)[poly(BFMPx-AV), (x = 4, 8, and 12)] were synthesized by Horner-Emmons reaction utilizing potassium tert-butoxide. Of these synthesized polymers poly(BFMP4-AV) and poly(BFMP8-AV), which has four and six methylene groups as solubility spacer in the main chain exhibited liquid crystalline to isotropic transition in addition to the two first order transitions. Light-emitting diode (LED)s made from the organic solvent soluble poly(BFMP12-AV) as emitting layer showed blue shift in the emission spectrum compared to the one made from fully conjugated poly(MEHPV-AV). Although poly(BFMP12-AV) had higher barrier to the electron injection from cathode than poly(MEHPV-AV), the luminance efficiency of LED made from poly(BFMP12-AV) was about 25 times higher than the one made from poly(MEHPV-AV), which had fully conjugated structure. LEDs fabricated by both poly(BFMP12-AV) and poly(MEHPV-AV) exhibited Stoke’s shift in the range of 155 to 168 nm from the absorption maximum due to the excimer formation between the ground and excited state anthracene groups. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Application of 146370-51-6

On November 21, 2001, Peng, Kang-Yung; Chen, Show-An; Fann, Wun-Shain published an article.Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Efficient Light Harvesting by Sequential Energy Transfer across Aggregates in Polymers of Finite Conjugational Segments with Short Aliphatic Linkages. And the article contained the following:

A series of light-harvesting polymers (poly-DSBs) of dialkyloxy- or dialkyl-substituted distyrylbenzene ( substituents = methoxy, 2-ethylhexyloxy, and cyclohexyl) with methylene or ethylene spacers were prepared The interactions between lumophores and the role of chem. structure of poly-DSBs on the absorption, emission, and excitation spectra were studied. The proximity of distyrylbenzene lumophores was critical to effective interactions and to the energy-transfer processes. In concentrated solutions and solid films, intermol. aggregates exist resulting from different extents of interactions between lumophores and involve at least three species: loose, compact, and aligned aggregates as observed by photoluminescence and excitation spectroscopy. Sequential energy transfer was directly observed from individual lumophores to the most compact, aligned aggregates via looser intermol. aggregates by time-resolved fluorescence spectroscopy. This process mimics energy transfer in photosynthesis and is highly efficient; fluorescence can be red-shifted drastically by the presence of comparatively few aggregates and light from concentrated solutions and films of poly-DSBs is entirely or almost due to aggregation emission. Although sequential energy-transfer in fully conjugated electro/photoluminescent polymers due to inhomogeneity other than distributed conjugation length has never been directly observed at room temperature, events similar to those observed in poly-DSBs could occur but on a much shorter time scale, i.e., a few picoseconds. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene
