Molecular Recognition by a Silica-Bound Fullerene Derivative

摘要: Thermal ring opening of N-[3-(triethoxysilyl)propyl]-2-carbomethoxyaziridine in the presence C60 produces a fulleropyrrolidine derivative which is then attached covalently to HPLC silica gel. The new chromatographic material used investigate binding affinities potential hosts for immobilized C60. Exceptionally high size selectivities have been obtained cyclic oligomeric compounds like calixarenes and cyclodextrins organic water-rich media, respectively. A number rationally designed, helical-shaped peptides bind selectively grafted fullerene. most tightly bound peptide carries two ferrocene moieties at periphery hydrophobic cavity complementary
