π共轭平面分子的芳族叠层使其表现出独特的化学和物理性质。例如，盘状液晶是具有长烷基链的芳香化合物的柱状组合。有机导电材料涉及给电子和接受电子的π共轭化合物的交替电荷转移叠加。虽然这种无限组合已经被研究得很透彻，但由两个以上π共轭分子组成的精确控制的离散组合却很少被探索。本文报道了一种金属铰链有机柱笼的自组装，该笼具有可容纳两个大π共轭分子的大腔。笼子由两块大型有机板、三根杆状柱子和六个金属铰链组成（图1a）。大的箱形腔容纳有限数量的π共轭分子。
Introduction Aromatic stacking of π-conjugated planar molecules leads to the exhibition of unique chemical and physical properties. Discotic liquid crystals are, for example, columnar assembly of aromatic compounds with long alkyl chains. Organic electroconductive materials involve alternative charge-transfer stacking of electron-donating and -accepting π-conjugated compounds. Whereas such infinite assemblies have been thoroughly studied, precisely controlled discrete assemblies composed of more than two π-conjugated molecules are much less explored. Here we report the self-assembly of a metalhinged organic-pillared cage 1 with a large cavity which can accommodate two large π-conjugated molecules. The cage consists of two large organic panels 2, three rod-like pillars 3, and six metal-hinges 4 (Figure1a). The large box-shaped cavity accommodates π-conjugated molecules in limited numbers.
