Room-temperature phosphorescence and dual-emission behavior of simple biphenyl derivatives unlocked by intermolecular interaction with cyclic silver pyrazolate

The complexation of 4,4'-halogen-substituted biphenyls (BPs) with a trinuclear silver(I) 3,5-bis(trifluoromethyl)pyrazolate adduct ([AgL]3) is observed in the solution and the solid state. The infinite stacks are formed by alternatingly BPs...
