Gas-induced solid state transformation of an organic lattice: from nonporous to nanoporous
Journal Article

· Chemical Communications, 47(2):701-703
A well-known organic host, tris-o-phenylenedioxycyclotriphosphazene, exists in two polymorphic guest-free forms: the thermodynamic nonporous high-density phase and the kinetic porous low-density phase. Simple pressurization of the high density phase with CO2 brings a solid-state transformation to the low density phase. As a consequence, the crystal volume expands significantly by 23% with conformational change of the host molecules from Cs symmetry to D3h symmetry.
