The field of quinoidal molecules have been developed rapidly due to their superior electrical properties derived from more electron delocalized structure. One of the strategy for design of quinoidal molecules is the introduction of various quinoidal cores. We synthesized novel quinoidal conjugated polymers PmQEDOT-T2 and PmQEDTT-T2 including different atoms in the quinoid core through Stille polymerization. The prepared quinoidal conjugated polymers exhibited significantly different properties such as electronic, optical properties and vibronic structures. Organic field-effect transistors were fabricated using PmQEDOT-T2 and PmQEDTT-T2 polymers, the highest hole carrier mobilities of 7.1 x 10-2 and 1.4 x 10-2 cm2/Vs were obtained. In this study, we will explain the substitution effect of atoms on quinoidal conjugated polymers in relation to microstructural analyses and molecular packing structures of thin films as well as thermal, optical, electrical and electrochemical properties. |
