Abstract

A well-known organic host, tris-o-phenylenedioxycyclotriphosphazene, exists in two polymorphic guest-free forms: the thermodynamic nonporous high-density phase and the kinetic nanoporous low-density phase. Simple pressurization of the high density phase with CO2 brings a solid-state transformation to the low density phase, resulting in significant expansion of the crystal volume by 23%.
