Sažetak
We are witnessing the problems of insufficient energy resources and environment pollution that have imposed a great challenge upon modern chemistry science. In a search for methodologies that would enable a clean and environmentally-friendly, while still economically accessible approach to design and construction of new materials, mechanochemistry is recognised as a method of choice. Recent discoveries in the field of solid-state reactivity such as liquid-assisted grinding (LAG)have promoted mechanosynthesis as genuinely a „green chemistry“ method far superior to the classical solution-based techniques. Moreover, an integration of mechanochemistry with modern solid-state analytical tools (structure solution from X-ray powder diffraction data - PXRD and solid-state NMR) [3] allows the entire search from synthesis and analysis to structural characterisation of a product to be conducted under a fully solvent-free conditions. In this presentation, a mechanochemical approach for the synthesis of zinc and cadmium complexes of cyanoguanidine will be described. We demonstrate the power of mechanosynthesis to screen for different stoichiometric compositions of metal-organic polymers and the use of a heteroditopic ligand to control the imensionality of such materials. By coupling the grinding synthetic methodology with PXRD and solid-state NMR characterisation tools we have achieved a complete implementation of the solvent-free paradigm in laboratory research.
