Abstract
This paper discusses the effect of number of units on bandgap for conjugation versus charge transfer system by using a conjugated polymer ([Zn])n and an unconjugated planar push–pull one (AQ–[Zn])n built upon 2,3-anthraquinone and bis(ethynyl)zinc(II)porphyrin. They are supported by DFT and TDDFT calculations, along with some experimental data. The position of the Q-bands is highly adjustable due to the presence of the twisted conformations in ([Zn])n chain.
