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

该项目包括两个子项目，涉及价互变异构金属-二恶烯烃配合物。1)合成具有锚定基团的新型双稳定钴-二恶烯烃，并将其化学接枝到金和氧化铝表面。所获得的表面沉积物将被热和光切换，允许在分子水平上控制二维材料的磁性。2)研究将价互变异构钴-二恶烯烃用作化学传感器的可能性。不同种类的单齿和双齿配体将在室温溶液中用作传感实验的底物。分子传感器将在视觉和磁场上做出反应。

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.
