Development of a soft crystallization method by using a crystalline nano-channel with molecular arrangement ability

Porous crystals, Palladium Complex, Molecular Arrangement, Molecular Recognition, Single-crystal X-ray Diffraction

Research Outline

Our group has reported that a porous molecular crystal, Metal–Macrocycle Framework (MMF), possessing one-dimensional nano-channels with a 1.4 nm × 1.9 nm dimension is formed by the self-assembly of trinuclear palladium(II) complexes, and has also demonstrated that several guest molecules are site-selectively arranged in the nano-channel equipped with five enantiomeric pairs of molecular binding pockets. In this project, utilizing the MMF channel as a nano-sized crystallization place, we aim to develop a “soft-crystallization method” that can flexibly crystallize multiple molecules within the one-dimensional nano-space of MMF crystals. This method would lead to novel properties such as optical properties, electrical conductivity, and molecular transportation based on the specific crystal structures of various molecules within MMF.
