文摘
A novel noninterpenetrated metal鈥搊rganic framework [Cu2L(H2O)2]f路(DMA)18路(H2O)19 (ZJU-31, ZJU = ZheJiang University; H4L = 5鈥?5鈥测€测€测€?(2,5-dimethoxy-1,4-phenylene)bis[1,1鈥?3鈥?1鈥?terphenyl]-4,4鈥?dicarboxylic acid; DMA = N,N-dimethylacetamide) has been synthesized and structurally characterized from an expanded organic linker. Interestingly, although the new linker is larger than the developed one for the construction of ZJU-30 with a doubly interpenetrated structure, the incorporation of a 1,4-dimethoxyphenyl group into the new linker enforces the formation of noninterpenetrated ZJU-31. Accordingly, the activated ZJU-31a shows a much higher porosity with a BET surface area of 1115 m2/g than ZJU-30a of 228 m2/g. ZJU-31a exhibits highly selective separation of C2 hydrocarbons over C1 methane at room temperature.
