Growth in a confined environment : A protocol for the amorphous‐to‐crystalline transformation (ACT) of nanoparticles has been developed, the critical step being the partial confinement of the particles by fixing in a polymer thin film and solvent vapor fuming. The ACT of a diaminodicyanoquinodimethane‐based nanoparticle is accompanied by substantial fluorescence enhancement and switching of the emission color.
