摘要
A julolidine-based boron-phenylpyrrin small molecule has been designed and synthesized through a one-pot condensation-complexation procedure. Systematic optical studies show that this compound displays two distinct optical responses to the addition of HCl and Fe3+ in succession: the addition of HCl induces an obvious red shift in its maximum absorption and fluorescence emission bands accompanied with the fluorescence quenching, whereas after synchronously adding H+ and Fe3+, the maximum absorption and fluorescence emission wavelength were found to shift little but with an obvious decrease in the absorbance and fluorescence intensity, suggesting the dual-detecting nature of this compound to H+ and Fe3+ under acid conditions. More interestingly, based on the HCl/Fe3+-mediated absorption and fluorescence signal features, JBPP can function as AND, NAND, INH and IMP logic gates, which can be further developed into a 2: 4 digital demultiplexer. These will endow this small molecule compound with great potential for applications in molecular logic material, chemosensors and biological fields.
