摘要:
Two types of hexameric metallomacrocycles, [Zn-6(1)(6)(PF6)(12)] and [Zn-6(2)(6)(PF6)(12)], where 1 is 1,3-bis(2,2':6,2 ''-terpyridine)-5-tert-butylbenzene and 2 is 1,3-bis(2,2':6',2 ''-terpyridinylethynyl)-5-tert-butylbenzene, were self-assembled by capitalizing on terpyridine-Zn(II)-terpyridine connectivity. Their structural compositions were established by H-1 and C-13 NMR, UV-Vis, and mass spectrometry. Incorporation of an ethynyl group in the metallomacrocycle can play a role as an electron trapping site to enhance the molar extinction coefficiency and photocurrent generation.
