Light-induced spherical to dumbbell-like morphology transition of coumarin-functionalized latex nanoparticles by a [2π + 2π] cycloaddition reaction: a fast and facile strategy to anisotropic geometry

Abstract

Light-induced morphology transition of the functionalized spherical nanoparticles to anisotropic structures was achieved by dimerization of the surface coumarin molecules, which resulted in decreasing fluorescence intensities of coumarin moieties.
