Abstract

The photophys. properties of a supramol. donor acceptor dyad consisting of an oligo(p-phenylenevinylene) unit and a perylene-diimide unit are described. The dyad is created by functionalizing the two chromophores with quadruple hydrogen bonding 2-ureido-4[1H]-pyrimidinone units, which provide a high assocn. const. (K ~ 108 M 1 in toluene). This feature enabled the authors to study the time-resolved photoinduced singlet-energy transfer reaction between the two chromophores in dil. soln. with transient pump-probe spectroscopy. This energy transfer occurs with a time const. of 5.1 ps. [on SciFinder (R)]
