摘要

Two novel anionic single-walled metal-organic nanotubes (MONTs),[(CH3)2NH2][In(cdc)(thb)]·2DMF·9.5H2O (FJU-105) and[(CH3)2NH2][In(cdc)(H-btc)]·2DMA·11H2O (FJU-106) (H2cdc =9H-carbazole-3,6-dicarboxylic acid,H2thb =2,5-thiophene dicarboxylic acid,H3btc =1,3,5-benzene tricarboxylic acid),are achieved by employing[In6(cdc)6]6+ metalloring cluster with largest diameter as the secondary building blocks (SBUs).The inner surface of FJU-106 is functionalized by uncoordinated-COOH groups of the H-btc linkers,leading to a higher proton conduction than FJU-105.At 70 ℃,FJU-106 displays the proton conduction performances among MONTs,up to 1.80 × 10-2 S·cm-1.And FJU-105 and FJU-106 are the first examples of MONT proton conductors operating at subzero temperature.
