Effective signal control (off-on-off action) by metal ionic inputs on a new chromoionophore-based calix[4]crown
Abstract
A new chromoionophore-based calix[4]crown 1 possessing an effective ‘off-on-off’ signalling for metal cationic inputs has been developed, the controllable signal function of which may not only be welcome for molecular information processing but also contribute to the design of new sensory materials.
