Crystalline aggregates formed by self‐assembly of organic small molecules have aroused intensive attention in many fields due to their controllable morphologies and functionalization. The advantages of intramolecular charge transfer (ICT) compounds endow them with the ability to self‐assemble into diverse dimensional crystalline microstructures, as potential candidates for advanced materials and smart miniatures in practical applications. In this review, the recent progresses of self‐assembled microstructures of functional ICT molecules in our group for a decade are summarized. The factors influencing the fabrication of the microstructures in solvent‐involved processes are fully discussed. Distinct optical properties induced by self‐assembly behaviors are also depicted. We try to give an outlook of structure‐property relationships in functional microstructure engineering and clarify the crucial issues to be addressed in the future scientific research.

“…These synthetic AIEgens generally display concentration-enhanced emission and aggregation-induced emission (AIE) characteristics. Given the presence of these systems, the clustering-triggered emission (CTE) mechanism could help explain the photophysical processes of these synthetic AIEgens ( Hu et al, 2020b ; Lu et al, 2020 ).…”

Aggregation-induced emission (AIE) molecules have garnered considerable interest since its first appearance in 2001. Recent studies on AIE materials in biological and medical areas have demonstrated that they show their promise as biomaterials for bioimaging and other biomedical applications. Benefiting from significant advantages of their high sensitivity, excellent photostability, and good biocompatibility, AIE-based materials provide dramatically improved analytical capacities for in vivo detection and demonstration of vital biological processes. Herein, we introduce the development history of AIE molecules and recent progress in areas of biotesting and bioimaging. Additionally, this review also offers an outlook for the potential applications of versatile AIE materials for tracing and treating pathological tissues, including overcoming challenges and feasible solutions.

“…The development of aggregation-induced emission luminogens (AIEgens) has become an active area of research since aggregation-induced emission (AIE) was first discovered by Tang and coworkers. [1][2][3][4][5][6][7][8][9] Owing to the unique properties of AIEgens with highly bright fluorescence emission in solid states, the potential applications have been extensively developed in various areas, such as organictransistor, [10] stimuli-responsive materials, [11] chemosensors, [12] biosensors, [13,14] etc. Therefore, many AIEgens have been broadly explored and systematically developed from some classical AIE building blocks, such as hexaphenylsilole, [15][16][17][18] tetraphenylethene (TPE), [12,[19][20][21] anthracenederivatives [22][23][24] and so on.…”

The development of aggregation‐induced emission luminogens (AIEgens) has attracted increasing attention due to their potential applications in various areas in recent years. In this study, a facile conversion from aggregation‐caused quenching (ACQ) to aggregation‐induced emission (AIE) was achieved by an efficient regioisomerization strategy based on the rofecoxib scaffold. Two compounds, named PYR2 and PYR4, were identified as regioisomers of rofecoxib derivatives to show dramatically different fluorescent properties. Compound PYR2 with an ortho‐substituted piperidine group showed typical AIE activity while compound PYR4 with a para‐piperidine group exhibited typical ACQ behavior. Notably, compound PYR2 showed polymorphism with two forms of crystals. It was also endowed with reversible mechanochromic luminescence and acidochromic properties. The different fluorescent properties were elucidated by UV/Vis absorption spectroscopy, powder X‐ray diffraction, differential scanning calorimetry, and thermogravimetric analyses. Its application as a security ink and in lipid droplets imaging have been demonstrated.
