Visible-to-UV photon upconversion in air-saturated water by multicomponent co-assembly

Abstract

Air-stable, visible-to-UV photon upconversion based on triplet-triplet annihilation (TTA-UC) in water has been an outstanding issue despite its importance in a wide range of applications. This is achieved by giving oxygen barrier properties to cationic acceptor self-assemblies through ion complex formation with anionic fatty acids, i.e., supramolecular crowding. This journal is
