Fluorescent supra molecular metal assemblies as 'no quenching' probes for detection of threonine in the nanomolar range

摘要

A highly sensitive detection of threonine is realized using a supra-molecular ensemble of aggregates of hetero-oligophenylene derivative 3 and Zn~(2+) ions. On the basis of fluorogenic response of aggregates of 3 toward Zn~(2+) ions and threonine, we have constructed a 2-input, 3-output sequential logic circuit at the molecular level.
