Potassium ion selective signaling based on intramolecular dimer formation of biscrown ether azochromophore - Chemosensor exhibiting forceps function

A novel bisbenzo-15-crown-5 azochromophore, 2, which exhibits forceps function, has been designed. 2 shows selective UV-vis spectral response for K+ in acetonitrile, which is based on the exciton interaction of the two azochromophores upon forming an intramolecular sandwich complex with K+.
