英文摘要	Porphyrin-or zinc-porphyrin-cyanuric acid conjugants (tpp-ca or zntpp-ca) and anthraquinone connected with the known "hamilton receptor" (aq-h) were synthesized. the supramolecular dyads constructed via the aq-h and tpp-ca/zntpp-ca exhibit six hydrogen bonds, which provide the association constant kapp approximately (2.8 +/- 0.3) x 103 mol(-1)center dot l in toluene. selective excitation of the porphyrin/zinc porphyrin chromophores results in an electron transfer between tpp-ca/zntpp-ca and aq-h within the supramolecular assemblies, leading to an efficient quenching of the tpp-ca/zntpp-ca fluorescence. the singlet electron transfer from porphyrin/zinc-porphyrin to anthraquinone proceeds mainly via a 'through space' mechanism with efficiencies of 43%, 58%, and rate constants of 7.6x10(7), 7.0x10(8) s(-1), respectively.
