Synthesis and characterization of high performance polymeric materials: poly(arylene ethers), polyamides, polyesters and liquid crystalline polyarylates
… both random and block copolymers to be prepared. Triaryl phosphine oxide containing homo-& co-PAEs exhibited very high char yields, which suggested that these polymers were potentially flame-resistant materials. The AB type halogenophenols were also polymerized in the presence of diphenylsulfone …

Towards next-generation degradable polymers via double amplification
… results showing that electron rich 2,4,6-triaryl-(1,3,5)triazaadamantanes underwent thermal decomposition in water. When a triveratryl-substituted analog was heated in the presence of bisphenol-A-diglycidyl ether, no curing was observed. When the curing was conducted at room temperature, …

Carbazole-based porous organic polymers for photocatalytic hydrogen evolution
… was introduced bearing an electron deficient triaryl borane core coupled to three carbazole groups. The resulting monomer proved to be highly emissive with a highly polarized excited state. Due to polymerization the absorption shifted from the UV region to the visible light region, which is …
