The development of mechanoluminescence from organic compounds: breakthrough and deep insight

Abstract

The organic mechanoluminescence (ML) compounds have experienced breakthrough development in recent years, with the ML being discovered in many kinds of organic compounds. Accordingly, the ML composition is becoming more complicated, from the initial stage of nitrogen discharge, to the fluorescence, dual emission of fluorescence and phosphorescence, and the more novel persistent room-temperature phosphorescence (RTP), photo-sensitive ML, presenting the unique luminous properties with more perspectives. Since ML is found to highly correlate with the molecular configuration and the intermolecular packing style in aggregate state, the photophysical properties should be analyzed carefully with the consideration of MUSIC (Molecular Uniting Set Identified Characteristic). In this review paper, we summarized the recently reported organic ML compounds, which were classified according to their luminous and chemical structure features. The investigation on organic ML should promote the development of the “aggregate chemistry” and the luminous theory in aggregate state.
