与以往的主-客体配位系统不同，通过Pt（II）连接的配位胶囊在水中包被各种荧光染料（如BODIPY和香豆素衍生物），成功制备了高发射的主-客体配合物（高达Φ(F) = 0.5）。皮秒时间分辨光谱阐明了所获得的配合物的光物理行为。值得注意的是，在所述胶囊内的荧光客体的发射颜色可以在与平面芳香分子成对包封后容易地进行调制。
Unlike previous coordinative host-guest systems, highly emissive host-guest complexes (up to Φ(F) = 0.5) were successfully prepared upon encapsulation of various fluorescent dyes (e.g., BODIPY and coumarin derivatives) by a Pt(II)-linked coordination capsule in water. Picosecond time-resolved spectroscopy elucidates the photophysical behaviors of the obtained complexes. Notably, the emission color of the fluorescent guest within the capsule can be readily modulated upon pairwise encapsulation with planar aromatic molecules.
