N′-dialkylimidazolidine-2,4,5-trithione complexes ([Ni(R2timdt)2]) carrying linear or branched carbon chains (R = n-C4H9, n-C8H17, n-C12H25, n-C16H33, 2-ethylhexyl, 2-butyloctyl, phytanyl) have been obtained through an original synthetic pathway starting from easily available imidazolium-based ionic liquids. The chemical structures of these nickel complexes were confirmed by NMR and high-resolution
一系列新的带有线性或支链碳链(R = n -C 4 H 9,n -C )的镍N,N'-二烷基咪唑烷-2,4,5-三硫酮络合物([Ni(R 2 timdt)2 ])8 H 17,n -C 12 H 25,n -C 16 H 33(2-乙基己基,2-丁基辛基,植烷)是通过容易获得的基于咪唑鎓的离子液体从原始合成途径获得的。这些镍配合物的化学结构已通过NMR和高分辨率质谱以及对单晶进行的X射线分析得到了证实。配合物在1000 nm附近的近红外(NIR)区域强烈吸收,其高消光系数达到80 000 M –1 cm –1。它们能够以非常高的光热转换效率(大约30%)在激光照射下将NIR光有效地转换为热量。
