| 摘 要： | The excited-state dynamics of a bisimide derivative (ZI) and a novel Z1-C60 complex (PSF) has been investigated by means of steady state optical spectroscopies and femtosecond time-resolved absorption spectroscopies. The lifetime of the singlet excited state of Z1 shortens drastically from 2.4 ns to 1.7ps upon going from Z1 to PSF, a significant kinetics change is in coincidence with the complete fluorescence quench caused by the C^60 attachment.Highly efficient Zl-to-C60 excitation energy transfer which is governed by the mechanism of Z1-C60 electron exchange has been verified for the PSF complex.

| Abstract: | The excited-state dynamics of a bisimide derivative (Z1) and a novel Z1--C60 complex (PSF) has been investigated by means of steady state optical spectroscopies and femtosecond time-resolved absorption spectroscopies. The lifetime of the singlet excited state of Z1 shortens drastically from 2.4ns to 1.7ps upon going from Z1 to PSF, a significant kinetics change is in coincidence with the complete fluorescence quench caused by the C60 attachment. Highly efficient Z1-to-C60 excitation energy transfer which is governed by the mechanism of Z1--C60 electron exchange has been verified for the PSF complex. |
