Abstract:
Porous molecular crystals (PMCs) should function as new-generation functional porous materials, but the selective crystallisation of PMCs is still difficult. Herein we demonstrate that the liquid-liquid interface between the MeOH/H2O mixture and alkanes promotes the crystallisation of a Pt(ii)-based PMC, rather than the nonporous form. This new crystallisation method allows control of not only the porosity but also the luminescence of the Pt(ii) complex crystal.
