Crystal Flexibility Design through Local and Global Motility Cooperation.

摘要: Incorporating local mobility into a flexible framework promises to create cooperative properties unattainable in conventional soft porous crystal. In this study, we propose design strategy that integrates substituent moieties and crystal via intra-framework π-π interactions. This integration not only facilitates structural transitions but also gives the coordination polymers (PCPs) different guest-free structures depend on activation conditions. The incorporated flexibility material ability discriminate C6 alkane isomers based gate-opening behaviors. Thus, PCP has potential applications isomer separation, critical step petroleum refining process produce gasoline with high octane rating. strategy, ligand designability, offers new approach functional design.
