Usage

General Description

Heptadecan-9-yl 4-methylbenzenesulfonate is an organic compound that belongs to the class of benzenesulfonates. It is a derivative of heptadecanol and 4-methylbenzenesulfonic acid, typically used as a surfactant in various industrial and household products. This chemical compound is known for its ability to lower the surface tension of liquids, making it useful in a wide range of applications such as in cosmetics, detergents, and industrial cleaning solutions. Additionally, it also acts as an emulsifier and stabilizer, allowing for the proper mixing and dispersion of immiscible substances. Despite its widespread use, heptadecan-9-yl 4-methylbenzenesulfonate should be handled with caution as it may cause skin and eye irritation, and prolonged exposure could lead to adverse health effects.

Bridging Small Molecules to Conjugated Polymers: Efficient Thermally Activated Delayed Fluorescence with a Methyl-Substituted Phenylene Linker

Based on a “TADF + Linker” strategy (TADF=thermally activated delayed fluorescence), demonstrated here is the successful construction of conjugated polymers that allow highly efficient delayed fluorescence. Small molecular TADF blocks are linked together

Carbazole-based π-conjugated polyazomethines: Effects of catenation and comonomer insertion on optoelectronic features

A series of carbazole-based polyazomethines have been synthesized under micro-wave irradiation and without transition-metal based catalyst. The impact of both the catenation brought by the carbazole subunits and the insertion of a co-monomer, i.e. 3,4 ethylene dioxythiophene (EDOT), on the optical and electrochemical properties have been studied. Among the different polyazomethines synthesized, the best in terms of optical and electrochemical properties has been found to be the one with the azomethine function linked in positions 2,7 of carbazole subunits. Upon the insertion of the EDOT comonomer, an increase of the molecular weight and a red-shift in the absorption spectra has been observed, corresponding to a diminution of the electronic gap.

A versatile approach to organic photovoltaics evaluation using white light pulse and microwave conductivity

State-of-the-art low band gap conjugated polymers have been investigated for application in organic photovoltaic cells (OPVs) to achieve efficient conversion of the wide spectrum of sunlight into electricity. A remarkable improvement in power conversion efficiency (PCE) has been achieved through the use of innovative materials and device structures. However, a reliable technique for the rapid screening of the materials and processes is a prerequisite toward faster development in this area. Here we report the realization of such a versatile evaluation technique for bulk heterojunction OPVs by the combination of time-resolved microwave conductivity (TRMC) and submicrosecond white light pulse from a Xe-flash lamp. Xe-flash TRMC allows examination of the OPV active layer without requiring fabrication of the actual device. The transient photoconductivity maxima, involving information on generation efficiency, mobility, and lifetime of charge carriers in four well-known low band gap polymers blended with phenyl-C61-butyric acid methyl ester (PCBM), were confirmed to universally correlate with the PCE divided by the open circuit voltage (PCE/Voc), offering a facile way to predict photovoltaic performance without device fabrication.
