“…Recently, a number of unique features of piezoluminescence have been reported such as high contrast, 7−9 multicolor swiching, 10 fullcolor tunability, 11 multiresponsive fluorescent probes, 12−14 hydrostatic pressure response, 15 far-red luminescence, 16 mesomorphic, 17 etc. Piezoluminescence is also reported for cocrystals 18 and organic salts. 19−21 These stimulus-responsive phenomena are due to the change in the crystal packing environment.…”

Piezoluminescence and liquid crystallinity of anthracene-based bispyridinium salts were investigated in stimulus-responsive luminescent organic crystals and luminescent ionic liquid crystals. The salts possess an anthracene moiety as a fluorophore in their center, and the pyridiniums attached to the anthracene moiety are substituted with trialkoxybenzyl groups. Single crystals of the salts bearing two trimethoxybenzyl groups were obtained as solvates. Ethyl acetate, acetone, and dioxane solvates of the chlorides have almost the same crystal structures with one-dimensional channels. Grinding of the solvated crystals caused the extrusion of the included solvent molecules, which resulted in the red shifts of their fluorescence in the solid state. The dimethyl sulfoxide solvate of the hexafluorophosphate also showed piezoluminescene by grinding. Tris(octyloxy)benzyl and tris(dodecyloxy)benzyl derivatives exhibited rectangular columnar liquid crystals upon being heated for their bromide and tetrafluoroborate salts and upon being cooled for their hexafluorophosphate salts. Of these pyridinium salts, hexafluorophosphates showed characteristic solvent-dependent fluorescence.

“…Besides, the boosted ησ 2 has also been realized upon the molecular aggregates owing to the higher quantum efficiency (η) of AIE effect. [168] Imaging [17] and fluorescence probe [169] are the two chief applications of the two-photon AIE molecules. Li et al presented to the conversion from the ACQ to AIE via adjusting the molecular packing mode through regioisomerization.…”

Aggregation‐induced emission (AIE) is a vital photophysical phenomenon that the luminogens in the concentrated or aggregated cases will engender the dramatically boosted emission in comparison with the dispersive states. Given this extraordinary emitting capacity exactly resolves the aggregation‐caused quenching (ACQ) situations residing in the traditional luminophores, the booming AIE luminogens have drawn tremendous interest owing to their advanced performances and colossal potential applications in various areas. Further exploitations of AIE molecules also drive the research interests in the midst of these AIE materials toward the nonlinear optical (NLO) regime. The combination of AIE and NLO effects have nurtured some unforeseen properties of AIE materials and extended their application spheres. Therefore, some NLO‐active AIE materials have been wielded in many crucial applications, for example, optical limiting, laser, bioimaging, and photodynamic therapy. Meanwhile, the impacts of aggregate on the NLO effect also deserve deep considerations and pursuits, and the modifications of aggregates promise an easy, efficient, and prompt avenue to tune the NLO properties of materials. The recent achievements and progress in the NLO properties of AIE materials have been summarized in this review. The second‐order and third‐order NLOs of the AIE materials have been introduced and their correlative applications have been discussed.
