Switchable Nanotubes Based on Resorcin[4]arene Scaffolds

Resorcin[4]arene cavitands having integrated quinoxaline wall flaps undergo marked rearrangements between an extended kite and a contracted vase form depending upon both temperature or pH. The current objective is to incorporate additional switchable components into the cavitands so as to facilitate clear geometric inter-conversions that are reversible and repeatable when exposed to the appropriate stimuli i.e., change in pH or temperature or exposure to different wavelengths of light. These novel dynamic responsive receptors/switches will be investigated for their shape-dependant host-guest complexation behavior, for guest sensing with the capability of optical readout, and for their potential as new read-write memory devices.
