Synthesis, Structures And Luminescent Properties Of Copper(â… )/Silver(â… ) Iodide Hybrids

Cu (â… )/Ag (â… ) metal halide hybrids have attracted more and more attention because of their structural features and novel optical, electrical and semiconductor properties. On one hand, high dimensional halide hybrids are rare due to the poor understanding of structural directing agents (SDA), on the other hand, Cul complexes reveal novel luminescent properties. This thesis will focus on the synthesis and characterization novel Cu(â… )/Ag(â… ) hybrid halides with high dimensional frameworks via deliberate choices of a series of organic amines. The as-synthesized compounds have been characterized by power/single-crystal X-ray diffraction, IR and photoluminescent properties and so on. The main results are as follow:1.Two cuprous iodide with chain and layer-like inorganic moieties directed by mono-protonated piperazine derivatives as organic structural-directing agents, which reveal interesting structural features and photoluminescence.2.Five copper(â… )/silver(â… ) iodides containing discrete clusters, one-dimensional chain directed by diprotonated piperazine derivatives as structural directing agents, in which the substituted groups, protonation extent and weak interaction between organic components display versatile directing effects.3. Four copper iodides composed of Cu4I4cluster motives and piperazine derivatives as ligands, which show different luminescence thermochromism.
