Geometrically twisted intra–inter-molecular cooperative interactions for an enhanced photo-response in an ORMOSIL-based host–guest system

Abstract

In situ encapsulation of the 2-(2′-hydroxylphenyl)benzothiazole (HBT) fluorophore into organically modified silica (ORMOSIL) is recognized as a potential approach to increase the photocurrent conversion efficiency. Encapsulation resulted in a twisted geometrical configuration of HBT with an efficient charge transfer and increased carrier density, resulting in a 246% photo-response enhancement.
