An unusual lamellar framework constructed from a tetracarboxylatocalix[4]arene with highly efficient metal-ion exchange

Abstract

Three novel tetracarboxylatocalix[4]arene-supported compounds, [(CH3)2NH2][Zn2(TCC4A)(μ3-OH)]·H2O (1), (NH4)4[Zn2(TCC4A)2(H2O)2]·11H2O (2), and [Cd2(TCC4A)(DMF)2(H2O)]·H2O (3) (H4TCC4A = 2,8,14,20-tetra-pentyl-6,12,18,23-tetra-methoxy-4,10,16,22-tetra-carboxymethoxy-calix[4]arene), have been synthesized. Compounds 1–3 display similar 2D sandwich layers in which tetranuclear metal clusters could be found in compounds 1 and 3. Remarkably, compound 1 displays an exchange of metal ions while retaining its framework and crystallinity. The Cu(II)-exchange process of 1 was monitored by ICP and PXRD. The luminescence properties of the H4TCC4A ligand and relevant compounds were studied in detail. The magnetic behavior of 1a has also been investigated.
