Synthesis, properties, and switching of valence tautomeric metal complex in solution, solid state, and self-assembled monolayers: from photoswitches to chemosensors

该项目包括两个关于价态互变异构金属-二氧戊环配合物的子项目。1)新型的钴二氧杂环戊烯具有锚定基团将被合成和化学接枝到金和氧化铝表面。所获得的表面沉积物将通过热和光进行切换，从而允许在分子水平上控制2D材料的磁性。2)将研究利用价态互变异构钴-二氧戊环作为化学传感器的可能性。不同种类的单齿和双齿配体将被用作室温下溶液中的传感实验中的底物。分子传感器会有视觉和磁性的反应。

The project encompasses two subprojects dealing with valence tautomeric metal-dioxolene complexes. 1) Novel bistable cobalt-dioxolenes featuring anchoring groups will be synthesized and chemically grafted to gold and aluminium oxide surfaces. The obtained surface deposits will be switched thermally and with light allowing the control of magnetic properties of 2D materials at the molecular level. 2) The possibility to use valence tautomeric cobalt-dioxolenes as chemical sensors will be studied. Different classes of monodentate and bidentate ligands will be used as substrates in sensing experiments in solutions at room temperature. The molecular sensors will respond visually and magnetically.
