选择性地获得了由4-吡啶-1,3-茚二酮二聚体1组成的1闭1开可转换分子晶体。热去除溶剂分子在1开1关。在特定的溶剂中进一步浸渍后再现1开。尽管这两个过程都涉及到分子包装排列的剧烈变化，但未观察到结晶度损失。
Interconvertible molecular crystals 1close and 1open composed of 4-pyridyl-1,3-indanedione dimer 1 were selectively obtained. Thermal removal of solvent molecules in 1open afforded 1close. Further dipping of 1close in a specific solvent reproduced 1open. No crystallinity loss was observed even though both processes involved a drastic change of molecular packing arrangements.
