摘要: Abstract α-, β-, and γ-cyclodextrin derivatives (cyclodextrin is abbreviated as CD, hereafter) bearing an dansyl or dansylglycine moiety at the primary secondary side of CD were synthesized fluorescent indicators for molecular recognition. The CDs with hydroxy have asymmetric cavity a distorted framework because conversion one glucose member to altrose residue effects this distortion ring on sensing abilities examined, compared case symmetrical side. results demonstrate that asymmetrical are unfavorable accommodate guest species due narrowed by distortion, contrasting observation exhibit remarkable various guests.
