Complex 1 crystallizes in the space group Pbcn, with a = 28.906(3), b = 13.5294(14), c = 17.8727(18) A, V= 6989.7(12) A^3, C66H48CdCl2N8, Mr = 1136.42, De = 1.080 g/cm^3, F(000) = 2328, μ= 0.428 mm^-1 and Z = 4. Complex 1 features a 2D → 3D framework with the coexistence of inclined polycatenation and polythreading. In addition, the luminescent property of complex 1 was studied.展开更多

FOF-1 is further applied to construct a polycatenane framework FOF-pc-1 through the quantitative cucurbit[7]uril encapsulation for the diphenylbipyridinium subunits of the framework by making use of the dynamic nature of the hydrazone bond in water. The bipyridinium subunits in both frameworks can be reduced their radical cation counterparts to produce conjugated radical cation-linked dynamic organic frameworks rc-FOF-1 or rc-FOF-pc-1. Polycatenation is revealed to enhance the stability of the dynamic frameworks in water, whereas depolycatenation can be reached for both FOF-pc-1 and rc-FOF-pc-1 by using a ferrocene guest to form a more stable complex with CB[7].展开更多
