Key Points

The research aims to develop cocrystals that exhibit switchable solid-state emission by manipulating photophysical pathways.
Utilized a crystal-engineering approach to synthesize GFP chromophore analogue cocrystals.
Investigated coformers' electronic and supramolecular effects on emission properties.
Analyzed emission color changes under varying conditions.
Demonstrated a switchable emission from green to orange to quenched states in the cocrystals.
Observed transitions influenced by intramolecular charge transfer and the structural arrangement of the cocrystal.
Highlighted the role of competing aggregation-induced emission (AIE) and aggregation-caused quenching (ACQ) pathways.

Implication

Crystal-engineering enables switchable solid-state emission in cocrystals, suggesting novel optical applications.

Abstract

We present a crystal-engineering approach enabling switchable solid-state emission (green → orange → quenched) in GFP-chromophore analogue cocrystals. Coformer’s electronic and supramolecular effect shifts the photophysical pathway: intramolecular CT in...
