摘要

In flexible co-ligand system, the P-handed [Cd(bpb)](n) and the M-handed [Cd(pda)](n) helical chains interweave mutually into a novel 3D coordination framework with diamondoid skeleton, namely, {[Cd(1,4-pda)(bpb)(H2O)]center dot H2O}(n) (1) [bpb = 1,4-bi(4-pyridyl)butane, 1,4-H(2)pda = 1,4-phenylenediacetic acid]. Interestingly, I D hydrophilic tunnel of I acts as a template for the formation of the P-handed 1D helical water chains, displaying molecular recognition and chirality transfer. The photoluminescent property and thermal stability of 1 were also discussed.
