摘要

The influence of pi-stacking on photoinduced electron transfer in a series of donor-acceptor molecules attached to a 3-fold symmetric scaffold was studied.The donor-acceptor unit is a DEA-PDI pair(DBA- N,N-diethylaniline;PDI=perylene-3,4:9,10-bis(dicarboximide)),in which the 4-position of DBA is covalently attached to the nitrogen atom of one imide of PDI.One,two,or three DEA-PDI units are attached to the para position of one of the phenyl groups of 1,3,5-triphenylbenzene,using the other PDI imide group to form mono-,bis-,and tris(DEA-PDI).These molecules demonstrate an increasing tendency to se Assemble into pi-stacked dimers in solution in the order mono(DEA-PDI)bis(DEA-PDI)is(DEA-PDI).Photoinduced electron transfer in both the monomers and self-assembled dimers was studied by femtosecond transient absorption spectroscopy.The charge separation(CS)and charge recombination time(CR)constants are found to be independent of pi-stacking aptitudes,while the transient spectral features differ significantly upon dimerization.The electronic interactions imposed by pi-stacking appear to change the energies of the ground,excited,and ionic states of DBA-PDI to a similar extent,which results in similar energies for CS and CR within the monomers and dimers.
