Organic Mechanoluminescence with Aggregation-Induced Emission

Abstract

Mechanoluminescence (ML) involves the emission of light from various organic and inorganic materials upon mechanical stimulus. In this review, we contemplate the advances of metal-free, purely organic ML compounds with aggregation-induced emission (AIE), which give strong emission upon mechanical force. We show the new ML-AIE based materials can be used explore the basic of ML properties with structure-property relationships and molecular interactions. The flourishing idea of ML-AIE may help to find the characteristic and elusive component of ML as it partners with AIE, which upgrades the emission property in solids or aggregates. Recent advances in ML-AIE information could increase the wide scope of research in this expanding area, as these materials have promising applications in different optoelectronic areas.

Keywords: aggregation-induced emission (AIE); emission; fluorescence; mechanoluminescence; piezoelectric effect.
