摘要：
The photophysical properties Of L-lysine-based polypeptides bearing porphyrin pendants were investigated. The intramolecular exciton-exciton annihilation resulting from the exciton migration among the porphyrin units deactivates the singlet excited state efficiently. It was revealed that the rate of the exciton migration depends on the polymerization degree.
