Dynamics of Photoinduced Energy Transfer in Fully and Partially Conjugated Polymers Bearing π-Extended Donor and Acceptor Monomers.

ABSTRACT: The photophysical properties of donor (D)-acceptor (A) polymers were studied by designing two types of polymers, (D-σ-A) _n and (D-π-A) _n , with non-conjugated alkyl (sp ³) and π-conjugated (sp ²) linkers using π-extended donor and acceptor monomers that exhibit planar A-D-A structures. The non-conjugated alkyl linker provides structural flexibility to the (D-σ-A) _n polymers, while the π-conjugated linker retains the rigid structure of the (D-π-A) _n polymers. Photoinduced energy transfer occurs from the large donor to acceptor units in both polymers. However, the photoinduced energy transfer dynamics are found to be dependent on the conformati
