Tuning Solid-State Emission with Molecular Torsion in Dibenzosuberenylidene-Derived Organic Dyes

This is the authors' abstract. We don't add key points for this paper.

The solid-state emission of organic compounds is required for many opto-electronic applications. However, it remains challenging to modify the emission properties of existing solid-state emissive organic frameworks, due to their inherently complicated structure-activity relationships. Herein, we report the design and construction of a new family of solid-state luminogens based on the dibenzosuberenylidene scaffold. The dyes exhibit interesting crystallization-induced emission enhancement (CIEE) behavior, which can be fine-tuned via easily implemented structural modifications to result in a range of fluorescence colors and intensities.
