A modular design approach has been utilized to develop molecular ‘pockets’ featuring three integrated components, namely a phosphorescent Pt(II)-π(organic) moiety, a suitable receptor group, and a rigid, conjugated connecting backbone, and the cavities therein are examined by NMR spectroscopy and an X-ray crystal structure. Their photophysical properties have been investigated; unusually for Pt-terpyridine derivatives, the complexes are luminescent (near-red 3MLCT emission) in solution at room temperature. It has been shown that their emissive characteristics are affected by the nature of the backbone component but not the receptor group.
我们采用模块化设计方法开发出了分子 "口袋",其中包含三个集成组件,即
磷光
铂(II)-π(有机)分子、合适的受体基团和刚性共轭连接骨架,并通过核磁共振光谱和 X 射线晶体结构对其中的空腔进行了研究。对它们的光物理特性进行了研究;与
铂-叔
吡啶衍生物不同的是,这些复合物在室温下的溶液中具有发光特性(近红色 3MLCT 发射)。研究表明,它们的发射特性受骨架成分性质的影响,而不受受体基团的影响。
