ON/OFF metal-triggered molecular tweezers for fullerene recognition

Producción CientíficaHerein, we report molecular tweezers for fullerene recognition based on 2,2′-bipyridine-bearing corannulene motifs. The syn or anti confirmation can be selected simply by Cu(I) coordination/decoordination, thus controlling the fullerene recognition capability of the system on demand and leading to the formation of effective metal-triggered ON/OFF molecular tweezers.We thank the Spanish Ministry of Science, Innovation and Universities (MCIU) for funding (project numbers PGC2018096880-A-I00, MCIU/AEI/FEDER, UE, PGC2018-099470-B-I00, and MCIU/AEI/FEDER, UE).
