【摘要】 金属-有机笼状化合物(MOCs)是一类具有特定空腔的离散型分子,由可修饰的有机配体与金属离子自组装而成。荧光素分子良好的荧光响应使其在荧光探针、追踪以及作为非贵金属光敏剂在光致产氢等领域有着重要的作用[1]。而将荧光素分子通过主客体作用包合在金属-有机笼状化合物的限域空腔内部,所构成的超分子体系有着更加优越的应用前景[2]。因此,我们合成了一例基于Co(Ⅱ)的MOC(Co-YL),该化合物中包含有多重酰胺基团以及仲胺基团作为作用位点,可与尺寸合适的荧光素分子形成主客体作用从而将其包合在Co-YL空腔内部[3]。更多还原

【Abstract】 Metal-organic cages(MOCs),discrete molecular architectures with well-defined cavities and multifunctional organic ligands,have attracted considerable attention.1 The encapsulation of Fl molecules as guests within the cavity of MOCs represents an excellent approach for constructing supramolecular systems exhibiting superiority in many applications.2 Herein,a well-designed MOC based on Co(II) ions was synthesized(Co-YL).By incorporating amide groups and secondary amine groups as interaction sites,Co-YL could encapsulate the size-suitable Fl molecules via host-guest behavior.3更多还原
