Electropolymerization of D-A type EDOT-based monomers consisting of camphor substituted quinoxaline unit for electrochromism with enhanced performance

In this study, three novel donor-acceptor type monomers based on EDOT (3,4-ethoxylene dioxy thiophene) and quinoxaline derivates were designed and synthesized through Stille coupling reaction, and further polymerized by electrochemical polymerization for electrochromic application. Specially, a quinoxaline-based acceptor with bulky and rigid camphor group was introduced into the polyEDOT backbone, which was demonstrated to be effective for the improvement of electrochromic performance. The corresponding redox active polymers PCQ-EDOT and PCQ-DEDOT performed transparent oxidation states and robust switching stability. Polymer PCQ-EDOT showed superior electrochromic performances with high optical contrast (over 50%) at 647 nm, short switching time (around 0.5 s) and high coloration efficiency (427 cm2 C?1) under a low applied potential of 0.7 V.

Method for producing camphorquinone by taking byproduct generated in camphor synthesis process as raw material

The invention provides a method for producing camphorquinone by taking a byproduct generated in the camphor synthesis process as a raw material, belonging to the technical field of organic synthesis.The byproduct 3-camphene ester generated in the synthesis process of camphor is used as a starting material to prepare high-purity camphorquinone through refining, saponification, dehydrogenation, condensation, hydrolysis and recrystallization steps. The method has the beneficial effects that the value of the byproduct generated in the camphor synthesis process is used, industrial wastes are reduced, wastes are changed into valuables, environmental pressure is reduced, a brand-new path for the synthesis of the camphorquinone is provided, no heavy metals are used in all process steps, truly nontoxic chemical synthesis of the camphorquinone is realized, and the method is an economic and environment-friendly production process.
