Efficient synthesis and physical properties of novel H-shaped 2,3,7,8-tetraazaanthracene-based conjugated molecules

Abstract

A series of novel H-shaped molecules consisting of a 2,3,7,8-tetraazaanthracene core and thiophene arms have been developed. The electrochemical study reveals their typical n-type characters. The solid state packing and optoelectronic properties of these molecules can be finely tuned via modification of the substituents.
