“…The mechanochromic nature of the above AIE/AEEgens is caused by the disruption of molecular packing and their transformation between crystalline and amorphous states. However, HPB‐5a, with an up to 630 nm emission wavelength in the solid state, exhibited three‐color switching via reversible chemical reactions, as shown in Figure D. The three compounds were easily obtained by mixing ( E , E )‐HPB‐5 and tri(pentafluorophenyl)‐borane (BCF) in dichloromethane or by grinding together and by reacting ( E , E )‐HPB‐5a with methanol in the presence of BCF to derive acetal‐substituted ( E , E )‐HPB‐5 with a 530 nm emissive wavelength; that is, the transformation of the aldehyde into an acetal was easily achieved in the presence of BCF. Both processes are fully reversible and can return to ( E,E )‐HPB‐5 with a 550 nm emissive wavelength by heating or fuming.…”

Organic functional materials, including conjugated molecules and fluorescent dyes, have been intensely developed in recent years because they can be applied in many fields, such as solar cells, biosensing and bioimaging, and medical adjuvant therapy. Organic functional materials with aggregation-induced emission or aggregation-enhanced emission (AIE/AEE) characteristics have increasingly attracted attention due to their high quantum efficiency in the aggregated or solid state. A large variety of AIE/AEE materials have been designed and applied during the exponential growth of research interest in the abovementioned fields. Multiphenyl-substituted 1,3-butadiene (MPB), as a core structure that includes tetraphenyl-1,3-butadiene, hexaphenyl-1,3-butadiene and their derivatives, show a typical AIE/AEE feature and can be potentially used in all the above-mentioned fields. This review summarizes the design principles, the corresponding syntheses, and the structure-property relationships of MPBs, as well as their excellent innovative functionalities and applications. This review will be useful for scientists conducting chemistry, materials, and biomedical research in AIE/AEE-related fields.

Multicolor emissive materials consisting of as ingle luminophore,aLewis acid, and their complex were developed. The emission colors can be tuned by changing the concentration of the solution and the ratio of mixed solvents.V arious emission colors in the solid state were observed when the complexes were added to polymers in different amounts.T he color change is due to equilibrium disruption between the single luminophore,t he Lewis acid, and the complex thereof. White emission was observed by appropriately controlling the equilibrium by changing the amount of the complex in the polymer.
