Abstract:
Three novel carboxyarylphosphonate polymers {[Zn-2(PCP)(H2PCP)(phen)(2)]center dot H2O}(n) (1), [Zn(HPCP)(4,4 '-bipy)](n) (2), and [Zn-3(MCP)(2)(2,2 '-bipy)](n) (3) [PCP3- = p-O2C(C6H4)CH2PO33-, MCP3- = m-O2C(C6H4)CH2PO33- and phen = phenanthroline] were synthesized and characterized by single-crystal X-ray diffraction. Compound 1 features a butterfly-shaped dimer consisting of [Zn4P4O10] tetranuclear units, which are further linked by hydrogen bonds and pi-pi stacking interactions into a 3D supramolecular framework. In 2, there is an infinite P-O-Zn inorganic 2D (4,4) layer with the phosphonate moieties of HPCP2- and unidentate 4,4 '-bipy ligands vertically sticking out. As for 3, the novel [Zn6P4O12] hexanuclear units with "chair" conformation are tetrahedrally bridged by eight MCP3- to generate a 2D double-layer, in which the windows are occupied by 2,2 '-bipy molecules. Additionally, 2D correlation analysis of FTIR with thermal perturbation of 3 were discussed. Compounds 1-3 exhibit intense solid state fluorescent emissions. Thermogravimetric analyses suggested the very high stability.
