Abstract Two urea-based porous organic frameworks, UOF-1 and UOF-2, were synthesized through a urea-forming condensation of 1, 3, 5-benzenetriisocyanate with 1, 4- diaminobenzene and benzidine, respectively. UOF-1 and UOF-2 possess good hydrophilic properties and high scavenging ability for palladium. Their palladium polymers, Pd II/UOF-1 and Pd II/UOF-2, exhibit high catalytic activity and selectivity for Suzuki–Miyaura cross- ...
