New fluorescent benzimidazolium-based receptors selectively display the effective fluorescence quenching effect for biologically important anions, GTP and I(-), in aqueous solution of physiological pH 7.4. These affinities can be attributed to the strong ionic H-bonding along with additional interactions of fluorophore moieties with the nucleic base of GTP and I(-).
新的荧光苯并咪唑基受体在生理 pH 值为 7.4 的水溶液中对生物上重要的阴离子 GTP 和 I(-)表现出有效的荧光猝灭效应。这些亲和力可以归因于与 GTP 和 I(-)的核酸碱基的强离子氢键以及荧光团部分的附加相互作用。
