Impact of the Position of Imine-Linker over Optoelectronic Performance of π-Conjugated Organic Frameworks

Abstract

Conjugated organic frameworks are interesting class of functional porous organic material having -conjugated backbone with permanent porosity. These materials are potential candidate for optoelectronic applications. Although there are several reports on structure-property relationship between π-conjugated building blocks and optoelectronic performance, however the influence of linker position is hitherto unknown. We report two novel imine linked 2D π-conjugated polymer which are positional isomers of each other comprising of pyrene and anthracene units. Both the polymers exhibits simillar optical and electronic properties under the ambient condition. Upon I2 doping, one of the isomer exhibited high radical density and enhanced conductivity due to energetically favoured chemical oxidation. The linker position dramatically affects the optoelectronic performance these polymers even though they have same -conjugated backbone.
