Turn-off fluorescence sensing of benzenediols via guest-induced π-conjugation switching in bisimidazole-based hydrindacene allosteric receptors
{{output}}
Fluorescent bisimidazole-based hydrindacene allosteric receptors 1a-c and 2 were synthesized for nonlinear ON/OFF sensing of benzenediols. By tuning their D-π-D conjugation through substituent modification, these receptors were designed to function as turn-of... ...
