Abstract
4,4-Difluoro-4-bora-3a,4a-diaza-s-indacene bridged bis(permethyl-beta-cyclodextrins) 1 was synthesized successfully through click chemistry, and it forms a well-defined linear assembly with 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin 2 via extremely strong host-guest interactions, which was identified by the methods of UV-vis, NMR, AFM, and TEM, respectively. Furthermore, the fluorescence resonance energy transfer from host spacer to porphyrin guest was investigated, showing that the energy transfer quantum yield is high to 94% in virtue of such a noncovalent path.
