The POx-solvent mixture was heated and then cooled to room temperature; by visual inspection, gels formed within several minutes. The formation of a strong gel was confirmed when it did not flow under its own weight upon vial inversion. I: insoluble/recrystallization/precipitate, S: soluble upon heating, S(p): partially soluble; G(s): strong gel, G(w): weak gel, G(p): partially gel.
