| 摘 要： | Ultra time-resoived huorescence spectra were used to study the energy transter processes and mechanism of complex PEC/PC/APC at 77 K, which was reconstructed with phycobiliproteins (PEC, PC and APC) of Anabaena variabilis, and has intact light-harvesting system and single terminal emitter. The energy transfer relationships between different chromophores especially between rod and core were also discussed based on fluorescence decay kinetic under different detected wavelengths. As a result, we got the possible energy transfer pathways and transfer time constants to be 29 ps between two PEC trimers, 12 ps between PEC and C-PC, 51 ps between rod and core.
