제목 An Isomer-free and Low-lying Energy Level Quinoidal Conjugated Polymer with Flat Thiophene Derivative Unit
초록 The development of isomer-controllable core containing quinoid materials has been considered as a main issue since the presence of geometrical isomers limits the systematic investigation of their chemicophysical properties. In this work, the isomer-free and low-lying energy level quinoid molecule bQuPheDOT was designed, then a quinoidal conjugated polymer PbQPheDOT-2FT2 was synthesized by using bQuPheDOT monomer. It was found that the prepared quinoid monomer bQuPheDOT exhibited only (Z, E, Z) single isomer configuration, accomplished by steric hindrance between aryl rings and electrostatic intramolecular interaction. The employment of phenyl rings in quinoid core had effects on decrease of the electron-releasing mesomeric effect into conjugated backbone as well as the enhancement of molecular packing. We will explain the effect of the introducing phenylene unit in quinoid core in relation to optical, electrochemical and charge transport properties for quinoidal polymers.
