First Triazole-Linked Porphyrin-Fullerene Dyads.

[摘要]：A general procedure for the synthesis of 1,2,3-triazole-linked porphyrin-fullerene dyads (I, II; Ar = 3,5-di-tert-butylphenyl) is described. The synthesis involves the prepn. of zinc porphyrins with a meso-appended [(formylphenyl)triazolyl]phenyl linker group followed by Prato 1,3-dipolar cycloaddn. to C60 of the azomethine ylides generated from the porphyrinic aldehyde and sarcosine. Four of these compds. were prepd. and characterized via 1H NMR, COSY NMR, MALDI-TOF mass spectra and fluorescence spectra.
