Mechanoluminescence, or the generation of light from materials under external force, is a powerful tool for biology and science. However, direct mechanoluminescence polymers remains limited. Here, we report novel design strategy mechanoluminescent that leverages synergy between masked 2-furylcarbinol mechanophore mechanically triggered release an adamantylidene-phenoxy-1,2-dioxetane chemiluminophore payload. Ultrasound-induced mechanochemical activation polymers, in both organic aqueous solutions, triggers cascade reaction ultimately results bright green emission. This capitalizes on modularity system combination with advances exceptionally highly tunable adamantylidene-1,2-dioxetane chemiluminophores. We anticipate this chemistry will enable diverse applications optoelectronics, sensing, bioimaging, optogenetics, many other areas.

Abstract Aromatic imides are an important class of organic mechanoluminescence (ML) compounds. Color is one the most ML properties, and it was previously modified by preparing various aromatic imide derivatives using chemical synthesis. In this report, we present a simple alternative strategy where single solution‐mixed crystallized with commercial dyes to produce mixtures that exhibit new colors. Specifically, blue in its pure form, could be changed pink, yellow, or weak white color Eosin Y, Fluorescein, Acridine Orange, respectively.
