“…Such an amorphous state was further confirmed by the flat signal in the powder XRD measurement ( Figure 5 ). Meanwhile, the red-shifted emission could be attributed to the collapse of the crystalline lattice by grinding, which resulted in the molecules adopting a more planar conformation [ 31 , 56 ]. Such an amorphous solid can be crystallized by either heating or fuming with an organic solvent vapor.…”

“…Fluorescence emissions can also be modulated by external stimuli. The type of stimulation can be divided into photochromic, electrochromic, thermochromic, mechanochromic, and so on [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. The emission properties of mechanochromic fluorescence materials can be controlled by physical channels, such as anisotropic grinding, shearing, or rubbing [ 36 , 37 , 38 , 39 , 40 ].…”

The development of mechanochromic fluorophors with high-brightness, solid-state fluorescence is very significant and challenging. Herein, highly solid-state emissive triphenylamine, carbazole and tetraphenylethylene-functionalized benzothiadiazole derivatives were developed. These compounds showed remarkable aggregation-induced emission and solvatochromic fluorescence characteristics. Furthermore, these fluorogenic compounds also displayed different mechanically triggering fluorescence responses.

Dedicated to Professor Daoben Zhu on the occasion of his 80th birthday The past one hundred years have witnessed the great development of polymer science. The advancement of polymer science is closely related with the development of characterization techniques and methods, from viscometry in molecular weight determination to advanced techniques including differential scanning calorimetry, nuclear magnetic resonance, and scanning electron microscopy. However, these techniques are normally constrained to tedious sample preparation, high costs, harsh experimental conditions, or ex situ characterization. Fluorescence technology has the merits of high sensitivity and direct visualization. Contrary to conventional aggregation-causing quenching fluorophores, those dyes with aggregation-induced emission (AIE) characteristics show high emission efficiency in aggregate states. Based on the restriction of intramolecular motions for AIE properties, the AIE materials are very sensitive to the surrounding microenvironments owing to the twisted propeller-like structures and therefore offer great potential in the study of polymers. The AIE concept has been successfully used in polymer science and provides a deeper understanding on polymer structure and properties. In this review, the applications of AIEgens in polymer science for visualizing polymerization, glass transition, dissolution, crystallization, gelation, self-assembly, phase separation, cracking, and self-healing are exemplified and summarized. Lastly, the challenges and perspectives in the study of polymer science using AIEgens are addressed.

“…Notably, fluorescent sensing has become a powerful tool for the detection of Hg 2+ (Kiani et al, 2020;Singh et al, 2020;Xu et al, 2020;Tian et al, 2020;Nan et al, 2021). Highly emissive materials in the aggregation state have drawn much attention because of their broad applications in chemical sensing, bioimaging, and photoelectric devices (Tong et al, 2014;Huang et al, 2014;Song et al, 2016;Tang et al, 2019;Zheng et al, 2019;Li et al, 2021;Cheng et al, 2021;Wang et al, 2021). However, traditional luminogenic molecules commonly suffer from a troublesome luminescence "aggregation-caused quenching (ACQ)" phenomenon (Mei et al, 2015).…”

A tetraphenylethene (TPE)-modified rhodanine derivative was successfully designed and prepared, and this luminophor showed intramolecular charge transfer nature from the TPE unit to the rhodanine-3-acetic acid unit. Interestingly, this luminogen not only exhibited typical aggregation-induced emission enhancement (AIEE) behavior but also showed good cell imaging performance. Remarkably, this AIEE-active TPE-containing rhodanine derivative possessed noticeable solvatochromic fluorescence effect involving multiple fluorescent colors of green, yellow-green, yellow, orange, and red. Meanwhile, this fluorescigenic compound displayed reversible mechanochromic fluorescence behavior based on the mutual transformation of between stable crystalline and metastable amorphous states. On the other hand, this multifunctional fluorophor could selectively and sensitively detect Hg2+ in an acetonitrile solution. Furthermore, this chemosensor could also be used to detect Hg2+ on test paper strips.
