Although mechanoluminescence (ML) phenomenon has been discovered for more than 400 years, it has not gone into the research focus once again until recent decades. This type of solid-state optical effect which is heavily dependent on molecular packing has been applied in some optoelectrical materials and possesses large potentials in the future high-tech fields. Currently, as the researches on organic functional materials flourish, more and more attentions have been transferred from ML-active inorganic, polymeric, organometallic compounds and ceramics onto ML-active crystals of purely organic small molecules. Due to the gradually deepened understanding for ML-active crystals of purely organic small molecules, the research interests have shifted from how to obtain ML-active compounds onto how to design and develop molecules so that ML-active purely organic crystals with differentiated ML behaviors can be produced. In this review, some methods for generating distinct ML performances, including physical adjustment, chirality activation, structural modification, polymorph formation, host-guest doping and so on are summarized. Meanwhile, how molecular packing and intermolecular interactions make impacts on ML effect in individual systems are also discussed herein and some constructive outlook about the future progress in aspect of ML study is accordingly proposed.

Key words: mechanoluminescence, crystals of purely organic small molecules, performances and adjusting methods
