1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene, abbreviated as TPBi, is a white crystalline solid containing three benzene rings and three benzimidazole rings in its chemical structure. It exhibits excellent light stability, thermal stability, and solubility. This compound forms aggregates in solution and exhibits favorable luminescent properties. It demonstrates high absorption in the ultraviolet region, effectively blocking UV penetration to safeguard material stability. TPBi finds extensive applications in chemistry, materials science, and optoelectronics. It serves as a fluorescent whitening agent when incorporated into plastics, rubber, paints, coatings, and fibers, enhancing material whiteness and brightness.
It is also commonly employed as a photo-antioxidant and light stabilizer to extend the service life of plastic and rubber products.
TPBi further finds application in optoelectronic devices, double-layer capacitors, photovoltaic materials, and related fields.
