A Multicontrolled Enamine Configurational Switch Undergoing Dynamic Constitutional Exchange.

A multiresponsive enamine-based molecular switch is presented, in which forward/backward configurational rotation around the C=C bond could be precisely controlled by the addition of an acid/base or metal ions. Fluorescence turn-on/off effects and large Stokes shifts were observed while regulating the switching process with CuII . The enamine functionality… CONTINUE READING
