论文摘要
从CO(II)BIS(4-羧基苯基)-2,2,2:6,2- terpyridine的高氯酸盐盐开始,通过化学溶液中直接组装单层的沉积是通过化学吸附来实现的。 MALDI-TOF MS,拉曼光谱和X射线光电子光谱(XPS)证实存在通过羧酸盐基团移植到Ag表面的完整的SCO分子单层。三种不同的光谱技术(拉曼,XP和X射线吸收光谱,XAS)证明了这种分子单层的热自旋跃迁。据我们所知,这是与通过湿化学获得的表面直接接触的主动SCO组件的第一个例子。
The deposition of a monolayer by direct self-assembly from solution of an active spin-crossover (SCO) complex via chemisorption has been achieved starting from the perchlorate salt of Co(II) bis(4-(4-carboxyphenyl)-2,2:6,2-terpyridine). MALDI-TOF MS, Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) confirm the presence of an intact monolayer of SCO molecules grafted through carboxylate groups to the Ag surface. Three different spectroscopic techniques (Raman, XPS and X-ray Absorption spectroscopy, XAS) evidence a thermal spin transition of such monolayer of molecules. To our knowledge, this is the first example of an active SCO assembly in direct contact with a surface obtained by wet chemistry.
