On January 12, 2021, Sun, Xiao-Wen; Wang, Zhong-Hui; Li, Ying-Jie; Zhang, Yun-Fei; Zhang, You-Ming; Yao, Hong; Wei, Tai-Bao; Lin, Qi published an article.Formula: C8H10O2 The title of the article was Tri-pillar[5]arene-Based Multifunctional Stimuli-Responsive Supramolecular Polymer Network with Conductivity, Aggregation-Induced Emission, Thermochromism, Fluorescence Sensing, and Separation Properties. And the article contained the following:

Multifunctional stimuli-responsive supramol. polymers have applications in the field of smart materials. Herein, a tri-pillar[5]arene-based multifunctional stimuli-responsive supramol. polymer network gel (SPN-DTG) was successfully constructed. Interestingly, the SPN-DTG shows excellent conductivity and tunable blue aggregation-induced emission (AIE) properties. Meanwhile, a series of metal-ion-coordinated supramol. polymer network gels (MSPNs) were successfully constructed by rationally introducing various metal ions into SPN-DTG. The xerogel powder of SPN-DTG shows excellent separation capacity for the removal of Fe3+, Hg2+, Cu2+, and Co2+ from water. More importantly, the Co2+-coordinated supramol. polymer network gel MSPN-Co shows intriguing thermochromic properties. The color of MSPN-Co could be reversibly controlled between light yellow and dark green by controlling the system temperature In addition, the Fe3+-, Hg2+-, Cu2+-coordinated supramol. polymer network gel MSPNs (Mn+ = Fe3+, Hg2+, Cu2+) show high selectivity and quick fluorescence response for I- and H2PO4-. Therefore, the SPN-DTG has applications in multifunctional smart materials with conductivity, AIE, thermochromism, fluorescence detection, and separation properties. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

Kucuk, Asuman C.; Matsui, Jun; Miyashita, Tokuji published an article in 2012, the title of the article was Proton-conducting electrolyte film of double-decker-shaped polyhedral silsesquioxane containing covalently bonded phosphonic acid groups.Synthetic Route of 929-37-3 And the article contains the following content:

As described phosphonic-acid-containing double-decker polyhedral silsesquioxane (PHOS-DDSQ) was synthesized and the p conductivity of the PHOS-DDSQ cast film was studied under humid and non-humid conditions. To synthesize PHOS-DDSQ, double-decker-shaped polyhedral silsesquioxane (DDSQ) was reacted with di(ethylene glycol) (DEG) vinyl ether using hydrosilylation reaction to attach 4 DEG units to one DDSQ (4DEG-DDSQ). Subsequently, a phosphate esterification of hydroxyl groups in 4DEG-DDSQ was carried out using POCl3. NMR, XPS, and MALDI-TOF MS spectra and titration measurements revealed that the phosphate esterification connected 2 DEG units to form a crown-ether-like structure. This structure prevents hydrolysis of the phosphate ester bond. PHOS-DDSQ showed high thermal stability, with decomposition temperature exceeding 220°, because of its inorganic DDSQ core. A uniform film of PHOS-DDSQ can be fabricated by drop casting. The cast film showed high p conductivity (0.12 S/cm) under humid conditions, which is comparable to that of a Nafion membrane. Also, the cast film offered good p conductivity under non-humid conditions (3.6 × 10-4 S/cm at 170°). The conductivity and thermal stability indicate that PHOS-DDSQ is a good candidate for use as a p-conductive membrane in hydrated type fuel cells as well as fuel cells operated at intermediate temperatures (100-200°) under non-humid conditions. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Synthetic Route of 929-37-3

Bitenc, J.; Dominko, R. published an article in 2020, the title of the article was Organic compounds as electrodes for rechargeable Mg batteries.Formula: C8H10O2 And the article contains the following content:

Redox-active organic materials were for the first time applied in a Mg bat- tery as a pos. electrode. Electrochem. tests showed some reversible activity with discharge voltages of around 1.4 V vs. Mg/Mg2+. However, it has to be noted that their tests were carried out in Mg electrolytes prepared from Grignard compounds, which means that the presence of nucleophilic species in the final electrolyte solu- tions cannot be excluded. Addnl., the use of copper current collectors could be problematic since it has been demonstrated that copper is prone to corrosion in chloride-containing electrolytes. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

On September 22, 2011, Murthy, A. V. R.; Goel, Mahima; Patil, Shivprasad; Jayakannan, M. published an article.Computed Properties of 146370-51-6 The title of the article was Probing the Role of Chain Length on the Diffusion Dynamics of π-Conjugated Polymers by Fluorescence Correlation Spectroscopy. And the article contained the following:

We investigate the role of the chain length and mol. weight distribution on the diffusion dynamics of freshly synthesized MEH-PPV polymer chains. For the above purpose, a new technique based on combination of size exclusion chromatog. (SEC) with fluorescence correlation spectroscopy (FCS) is developed to probe the diffusion dynamics of a narrow mol. weight distribution of fractionated samples of 20-500 kDa. The narrow dispersed samples were characterized by absorbance, emission, and time-resolved fluorescence decay techniques. The results revealed that the properties of fractionated samples were almost uniform for a wide range of mol. weights A maximum entropy based method for FCS data anal. is employed to obtain the correct diffusion coefficients of the polymer chains with heterogeneous dynamics. The FCS experiment on the unfractionated broad mol. weight sample is not enough to establish the correlation between the mol. weight of the chains with diffusion dynamics and emphasized the need for relatively monodispersed π-conjugated polymers. FCS results show that higher mol. weight chains diffuse much faster than shorter ones. Atomic force microscopy revealed that 300 kDa polymers produced 130 nm particles, whereas 50 kDa polymer chains formed micrometer size aggregates. At higher mol. weights, the strong chain interactions promote the formation of globular (or tightly packed) particles which diffuse faster in solution The low mol. weight chains experience strong interparticle interaction; as a consequence, the diffusion of chains becomes slower. In the present investigation, we demonstrate the need for the narrow polydisperse sample for establishing the correlation between diffusion dynamics and chain length (or mol. weights) of π-conjugated polymers using a single mol. spectroscopy technique such as FCS. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Computed Properties of 146370-51-6
