Abstract A wide variety of donor-acceptor(D-A) type small molecule dyad systems have been synthesized and studied to investigate the photophysical properties for a long time. However, the most studies used by the small molecules, the small molecule donor and fullerene acceptors system, and only a few studied exists that relates the physical properties of D-A type polymers. In this study, we have designed and synthesized the uniform macromolecular donor and acceptor monomeric units, and utilized them to synthesize two different type polymers such as, (D-σ-A)n and (D-π-A)n. (D-σ-A)n is a partially conjugated polymer, in which the donor is connected to the acceptor through a non-conjugated flexible alkyl spacer. Whereas, (D-π-A)n is a fully conjugated polymer, in which the donor is connected to the acceptor via π -conjugated spacer. Both polymer’s photophysical properties such as, fluorescence quenching, energy transfer and charge transfer were characterized via time resolved spectroscopy.
