Description

A donor-acceptor-donor type pi-conjugated small molecule, TPA-AIG-TPA, having an oligoether-functionalized azaisoindigo unit as an acceptor and triphenylamine units as donor groups was designed and synthesized. Its opto-electrochemical properties and charge transport applications were investigated. TPA-AIG-TPA demonstrated p-type transport behavior with a maximum carrier mobility of 0.12 cm2 V-1 s-1.
