摘要：

Two novel macrocyclic molecular probes linked to two nitrophenylurea and two nitrophenylthiourea groups, respectively, are reported. It was found that these systems can recognize different anions (OH-, F-, CN- with the nitrophenylurea probe, and OH-, F-, CN-, CH3COO- and H2PO4- with the nitrophenylthiourea probe) resulting in a red shift of electronic transition and correspondingly color-switching the probes. In addition, based on above sensing mechanism with the probes, IFNOT logic operations can be achieved using OH- and Cu2+ ion as inputs, and/or F- and Hg2+, respectively, making the probes, promising candidate for further applications in molecular logic devices.
