Configuration-independent AIE-active supramolecular polymers of cyanostilbene through the photo-stable host–guest interaction of pillar[5]arene

Author affiliations

Abstract

Supramolecular polymerization-enabled, configuration-independent aggregation-induced emission (AIE) systems of cyanostilbene were achieved through host–guest interactions between pillar[5]arene and nitrile triazole guests. Interestingly, host, control and control-guest lost its AIE upon photo-isomerization due to the absence of host–guest interaction. 1H NMR, DOSY NMR and fluorescence studies of the supramolecular polymers before and after UV irradiation clearly indicated the significant role of photo-stable host–guest interaction in enhancing and retaining AIE.
