摘要
Conformational control of the receptor-fluorophore orientation of BF2 chelated azadipyrromethene sensors reveals two photophysically different modes of analyte triggered fluorescence switching both of which exhibit large off-on fluorescence intensity responses to the fight input-output of the sensors in the visible red spectral region.
