Syntheses And Characterization Of Iodoargentate Frameworks With High Dimensionality Based On The Weak Interactions

Recently, the design and synthesis of iodometallate hybridshave attracted more and more attention owing to their structuraldiversity and potential applications. Especially, iodoargentates areof the most attractive for their uniquely tunable semiconductiveproperties. Therefore, it is very important to synthesize novelorganic-inorganic iodoargentate hybrids, and probe structuraldirecting mechanism and structure-property relationships.In this paper, directed by a series of cations with differentcharge, size, and shape, novel organic-inorganic iodoargentateswere synthesized. Basis on the initial characterization andcomparison with early research, conclusions are listed as follow:Firstly, supramolecular interactions can effectively modify theaggregation of structural directing agents. Secondly, band-gaps aremainly decided by iodoargentate structures, meanwhile conjugatedcations can increase the electronic mobilities which further lead tothe narrow band-gap. Lastly, third components existed in the latticenot only change the structural directing effects, but also affect the band-gaps of iodoargentate hybrids.
