title: A Mechanofluorochromic Push-Pull Small Molecule with Aggregation-Controlled Linear and Nonlinear Optical Properties.
abstract: A small push-pull molecule involving a diphenylamine substituted by an oligo-oxyethylene chain is described. The compound exhibits aggregation-induced emission with solvent-dependent emission wavelength. Spin-cast deep-red amorphous films rapidly self-reorganize into colorless crystalline films which exhibit mechanofluorochromism and aggregation-induced second-harmonic generation.
