On September 30, 1996, Cumming, W.; Gaudiana, R. A.; Hutchinson, K.; Kolb, E.; Ingwall, R.; Mehta, P.; Minns, R. A.; Petersen, C. P.; Waldman, D. published an article.Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Control of chromophore length in electroluminescent polymers. Part II. Mainchain polymers. And the article contained the following:

Electroluminescence emission has been demonstrated in mainchain polyesters and a structurally analogous polyamide. High-mol.-weight polyesters were synthesized by condensation of a dihydroxy-functionalized, substituted, phenylene vinylene analog, e.g., the lumophore, with a variety of dicarboxylic acid chlorides. The structure and hence the conjugation length of the emitting comonomer was predetermined prior to polymerization Since the diacid moieties did not contribute to the conjugation length and hence the emission wavelength, the structure of the diacid was determined on the basis of its ease of synthesis, reactivity, and solubilizing ability in the final polymer. In each of the polyesters, the electroluminescence wavelength of light-emitting diodes made from these polymers was similar to their photoluminescence emission spectrum in solution and the solid state at room temperature The emission wavelengths ranged from blue to green. The polyamide exhibits a very broad-band, nearly white electroluminescence. Diodes made from these polymers typically have external efficiencies ≤ 0.003% with low turn-on voltages, e.g., 6-20 V. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

On March 8, 2007, Jin, Youngeup; Jee, Jaesung; Kim, Kwanghyun; Kim, Jinwoo; Song, Suhee; Park, Sung Heum; Lee, Kwanghee; Suh, Hongsuk published an article.SDS of cas: 146370-51-6 The title of the article was Synthesis and electroluminescent properties of copolymers based on PPV with fluoro groups in vinylene units. And the article contained the following:

Electroluminescent copolymers with fluoro groups on vinylene units, poly(2-ethylhexyloxy-5-methoxy-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (MEH-PPV-co-DMOS-PPDFV) and poly(2-dimethyloctylsilyl-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (DMOS-PPV-co-DMOS-PPDFV), were synthesized by the Gilch polymerization route. The fluoro groups were introduced on vinylene units to increase the electron affinity of the copolymers. In both copolymers, the band gap increased with higher ratio of DMOS-PPDFV. As compared to the photoluminescence (PL) spectra in solution, the PL spectra in solid state and EL spectra of both copolymers showed red shift and broad peaks caused by aggregation. The LEDs fabricated using MEH-PPV-co-DMOS-PPDFVs emit light with maximum at around 538-577 nm. By adjusting the feed ratio of DMOS-PPDFV in the copolymer, the emission colors were tuned from orange yellow to green. The DMOS-PPV-co-DMOS-PPDFV showed maximum electroluminescence (EL) peaks at about 514-543 nm. The DMOS-PPV-co-DMOS-PPDFV with 1:9 feed ratio showed the highest luminescence efficiency of 1.31 lm/W. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).SDS of cas: 146370-51-6

And the article contained the following:

Light Emitting Polymers (LEPs) have gained attention in optoelectronics. However, stability and regulation of emission color remain a challenge. This study aims to overcome the challenge by formulating a Polymer Blend (PB) which consists of a LEP – poly [2-methoxy,5-(2-ethylhexyloxy)1,4-phynylenevinylene (MEH-PPV) and a non-conjugated polymer – poly(Me methacrylate) (PMMA). A simple approach of in situ polymerization of the non-conjugated polymer in the MEH-PPV solution leads to alteration of size of the MEH-PPV polymer chain and modified the emission color from red-orange to bluish-green. The barrier properties of PMMA improve the stability of PB in an ambient environment with unnoticeable luminescence loss. This type of PB shall find application in Organic Light-Emitting Devices. 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

And the article contained the following:

The booming of host-guest assembly-based supramol. chem. provides abundant ways to construct functional systems and materials. Attracted by the important application prospect of white light emission and aggregation-induced emission (AIE) materials, herein, we report an efficient way for fabricating metal-free white light-emitting AIE materials through the supramol. assembly of simple organic compounds: methoxyl pillar[5]arene (MP5) and tri-(pyridine-4-ylamido)benzene (TAP). By host-guest assembly, MP5 and TAP formed a supramol. polymer (MP5-T); meanwhile, the MP5-T xerogel powder emitted white light at CIE coordinates (0.29 and 0.29). The supramol. assembly and white light-emitting mechanisms were carefully investigated by experiments as well as quantum chem. calculations including d. functional theory (DFT), reduced d. gradient, electrostatic surface potential, independent gradient model, and frontier MO (highest-occupied MO-lowest-unoccupied MO) analyses. Interestingly, according to the experiments and calculations, the supramol. assembly is critical in the white light-emitting phenomenon. Moreover, in this work, the quantum chem. calculations could not only support exptl. phenomena but also provide deep understanding and visualized presentation of the assembly and emission mechanism. In addition, the obtained MP5-T solid powder could serve as a novel and easy means to make material for white light-emitting devices. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Related Products of 150-78-7

On October 5, 2022, Zhang, Xuepeng; Liu, Junkai; Chen, Biao; He, Xuewen; Li, Xueyu; Wei, Peifa; Gao, Peng Fei; Zhang, Guoqing; Lam, Jacky W. Y.; Tang, Ben Zhong published an article.Synthetic Route of 150-78-7 The title of the article was Highly efficient and persistent room temperature phosphorescence from cluster exciton enables ultrasensitive off-on VOC sensing. And the article contained the following:

Room temperature phosphorescence (RTP) materials have attracted wide attention due to their application potential in sensing, data-encryption, bioimaging, and optoelectronic devices. However, improving RTP efficiency and lifetime simultaneously in metal-free systems remains the biggest challenge for realizing their applications. Herein, by exploiting long-lifetime triplets of naphthalene (NL) and intersystem crossing (ISC)-promoting factors from 1,4-dichlorobenzene (DCB), we unveil a guest/host system (NL/DCB) with concurrently high RTP quantum yield of >20% and ultralong lifetime of >760 ms (duration ∼10 s) at ambient conditions. Based on systematic exptl. and theor. investigations, the underlying mechanism for efficient RTP of NL/DCB is mainly elucidated to be the formation of cluster excitons that boost ISC and triplet population of NL mols. Meanwhile, we showcase the first example of fast and ultrasensitive detection of a common hazardous VOC via turning on its ultralong afterglow by using NL/DCB RTP, opening another avenue for practical applications of purely organic phosphorescence. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Synthetic Route of 150-78-7

And the article contained the following:

Understanding how the conformational change of conjugated mols. with acceptor-donor-acceptor (A-D-A) architecture affects their phys. and optoelectronic properties is critical for determining their ultimate performance in organic electronic devices. Femtosecond-transient absorption, time-resolved upconversion luminescence spectroscopy, and tunable femtosecond-stimulated Raman spectroscopy, aided by quantum chem. calculations, was used systematically study the excited state structural dynamics of the intramol. charge transfer of the tetramethoxy anthracene-based fluorophore 2,3,6,7-tetramethoxy-9,10-dibenzaldehydeanthracene (AnDA) and its derivative 2,3,6,7-tetramethoxy-9,10-diphenylanthracene (TMDPAn) in CHCl3. In the AnDA mol., the tetramethoxy anthracene and benzaldehyde moieties exhibit a strong ability to donate and withdraw electrons. Upon photoexcitation, AnDA shows intriguing ultrafast fluorescence switch-on and red shift dynamics on charge transfer states, and the temporal evolution of AnDA recorded by ultrafast spectroscopy reveals a dynamic picture of 2-step intramol. charge transfer assisted by ultrafast conformational changes and solvation processes. Removing the aldehyde group from TMDPAn significantly decreases the electron pulling capacity of the Ph unit and disables charge transfer characteristics. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Category: ethers-buliding-blocks
