    Abstract: Silylene-spaced copolymers with alternating azacrown and anthracene moieties were synthesized
    for photoinduced electron transfer investigations. These polymers exhibited efficient intrachain photoinduced
    electron transfer with charge separation yield about 0.96-0.99 and corresponding charge-transfer rates around
    10.8-32.2 ns-1 in different solvents. Metal cations have been shown to enhance the fluorescence intensity due
    to complexation. These results are comparable to those of small molecules having similar chromophores. The
    geminal dimethyl substituents on silicon in these copolymers may direct the relative conformation (or distance)
    of the remaining substituents on silicon. Intrachain interactions between these chromophores may readily take
    place leading to highly efficient electron transfer processes.
