eng Substituted diphenylamino styryl benzenes as promissive materials with tunable intenzive solid state fluorescence – synthetic approach to key intermediate. The series of all-trans push-pull end-capped side-diphenyl substituted diphenylamino stylbenes (DPA-DPS-EWG) was prepared by Horner–Wadsworth–Emmons coupling. The important step of synthesis of targeted molecule is preparation of key intermediate: 5'-(1,3-dioxolan-2-yl)-[1,1':4',1''-terphenyl]-2'-carbaldehyde. There are existing several approaches for the synthesis of this molecule. Only some of them bring sufficient result for their synthesis. In this presentation, we would like to present our approach including unsuccessful experiments, our improvements as well as final experimental approaches to first investigated molecule and at the same time key intermediate for further modifications. diphenylamino styryl benzenes; solid state; fluorescence
