| 英文摘要 | several important photophysical properties of the cyanine dye cy3 have been determined by laser flash photolysis. the triplet-state absorption and photoisomerization of cy3 are distinguished by using the heavy-atom effects and oxygen-induced triplet -> triplet energy transfer. furthermore, the triplet-state extinction coefficient and quantum yield of cy3 are also measured via triplet-triplet energy-transfer method and comparative actinometry, respectively. it is found that the triplet -> triplet (t-1 -> t-n) absorptions of trans-cy3 largely overlap the ground-state absorption of cis-cy3. unlike what occurred in cy5, we have not observed the triplet-state t-1 -> t-n absorption of cis-cy3 and the phosphorescence from triplet state of cis-cy3 following a singlet excitation (s-0-s-1) of trans-cy3, indicating the absence of a lowest cis-triplet state as an isomerization intermediate upon excitation in cy3. the detailed spectra of cy3 reported in this paper could help us interpret the complicated photophysics of cyanine dyes. |
