Abstract

The effects of main and side chain modification of donor-acceptor conjugated polymers based on isoindigo and its derivatives on electrical properties were studied. The structure

morphology and electrical properties of the polymers were characterized by glancing angle X-ray diffraction

atomic force microscopy and Keithley 4200-SCS. The experimental results show that the addition of alkyl side chains can increase the steric hindrance and change the molecular stacking from the ordered edge-on structure to disordered

resulting in the decrease of crystallinity and electrical properties. The average hole mobility decreased from 0.05 cm

. However

when the long conjugated unit of benzofuradiadione (BIBDF) is used to replace the isoindigo unit in the main chain

the molecular stacking

crystallinity and electrical properties of the main chain are improved significantly due to the improvement of the planarity of the main chain

which don't affect the solution processability

and the polymer shows good bipolar transmission characteristics. The average mobility of electron and hole can reach to 0.29 cm
