英文摘要A series of oligo(phenylenevinylene)s (opvs) of different lengths containing aldehyde and dialdehyde groups on the ends were synthesized and characterized. their photophysical properties were also investigated via ultraviolet-visible, steady-state, and time-resolved fluorescence spectra. the results indicated that the absorption maximum, radiative rate constant, and excitation maximum of an opvncho oligomer series (where n represents the oligomeric length) showed linear relationships with the reciprocal number of conjugated units. similarly, the absorption maximum and emission lifetime of the oligomers of an opvn-2cho series showed linear relationships with the reciprocal number of conjugated units. the dependence of the fluorescence intensities of the opvs on the concentration of the quencher c-60 was evaluated. apparently, upon photoexcitation, the opvs underwent significant fluorescence quenching. the results for different opv derivatives and a quenching mechanistic discussion showed that the static quenching contribution was indeed responsible for the significant upward curvature.
