due to pH-induced conformational changes of the present molecules, the quenched fluorescence of the neutral states was turned-on. The redox behavior measured by cyclic voltammetry before and after protonation was contingent on the type of chromophoric unit incorporated into the dialdehyde segment. Owing to their ability to promote favorable, multifunctional properties, applications of these oligomers
