All the UV-vis spectra of the 2D polymers, PTPQT, PFPQT, and PCPQT, each with triphenylamine, fluorene, and carbazole units as the D2 side chain, possess strong intramolecular charge transfer absorption, thus resulting in better light harvesting. Their optical and electronic properties were thoroughly explored experimentally and computationally. The effect of molecular weight of the narrow polydispersity polymers on their optoelectronic property was studied in detail. In summary, the 2-D CPs show potential for use as an active material in optoelectronic devices. © 2014 Wiley Periodicals, Inc.[SDGs]SDG7Chains; Conducting polymers; Conjugated polymers; Electronic properties; Optoelectronic devices; Two dimensional; Conductive Polymer; Donor acceptor donors; Fractionation of polymers; Intra-molecular charge transfer; Optical and electronic properties; Optoelectronic properties; Renewable resource; Side chain structure; Polydispersityjournal article10.1002/pola.271072-s2.0-84897109332https://www.scopus.com/inward/record.uri?eid=2-s2.0-84897109332&doi=10.1002%2fpola.27107&partnerID=40&md5=e76fae9d150365af5e8ac569224c4e1c
