摘要：

In this work a unique hetero-metallic alkaline earth-transition Ba-Cd luminescent micro-porous metal-organic framework {[BaCd(mu(2)-t(P))1.5(mu(2)-Cl)(H2O) (DMF)(2)].0.75H(2)O}n (H(2)tp = terephthalic acid) (1) has been prepared under solvo-thermal conditions. In 1 infinite ID (Ba-X-Cd) (X = 0, CI) inorganic chains are linked via these full de-pronated tp2- ligands forming a unique 3D 1(1)O(2) type micro-porous coordination framework. PXRD patterns of 1 have been determined confirming pure phases of 1. Luminescence investigations suggested that 1 exhibits highly selective and sensitive sensing for trace amounts of benzaldehyde in ethanol, which provides a facile method for real-time detection of benzaldehyde. Meanwhile I also exhibits highly selective and sensitive sensing for Cu2+ over other cations with high quenching efficiency K-sv value 1.15 x 104 L.mol(-1). As far as we know, 1 represents the first example of alkaline earth-transition hetero-metallic Ba-Cd micro-porous coordination framework as bi-functional luminescent probes for Cu)+ and benzaldehyde.
