A pillar-layer MOF for detection of small molecule acetone and metal ions in dilute solution

A pillar-layer MOFs Cd(5-aip)L·3DMA (1) has been obtained under solvothermal conditions. 1 possesses non-interpenetrating pillar-layer framework with 1D rectangular-shape channels. The experimental results show that the luminescent intensity of 1 is highly dependent on metal ions and small solvent molecules, particularly Ni2+/Cd2+ ions and acetone.

Tubular porous coordination polymer for the selective sensing of Cu2+ ions and cyclohexane in mixed suspensions of metal ions via fluorescence quenching

A luminescent coordination polymer with tubular channels was synthesized and characterized. The polymer was able to sense small solvent molecules and metal ions via fluorescence quenching. In particular, the polymer was able to rapidly and selectively sense Cu2+ ions in a suspension of mixed metal ions without any interference effects.

Synthesis, structure and sensing behavior of a Cd-coordination polymer based on 1,10-phenanthroline and 2-aminoterephthalic acid

The reaction of 2-aminoterephthalic acid and 1,10-phenanthroline with Cd(NO3)2⋅4H2O under solvothermal conditions leads to the formation of [Cd(2-aip)(phen)]⋅0.5C2H5OH ( 1). In the compound, dimeta...

Rational design of a highly sensitive and selective "turn-on" fluorescent sensor for PO4(3-) detection.

An efficient turn-on fluorescent sensor for PO4(3-) has been developed by rationally designing an in situ-generated iron(iii) complex with a 1,8-naphthalene-based Schiff base unit. The sensor exhibits high sensitivity and selectivity in both solution and solid-state film, even in the presence of other phosphate anions such as HPO4(2-) and H2PO4(-).
