1. A molecularly-mixed composite membrane (MMCM) comprising:
a solution comprising:
a porous molecular material comprising porous organic cages (POCs); and
a polymer;
wherein the porous molecular material is dissolved in the polymer; and
wherein the porous molecular material is so uniformly distributed in the polymer as to form the solution as if it were a single-phase solution; and
wherein the MMCM is substantially defect-free, presenting:
a high level of homogeneity indicative of single POCs surrounded by the polymer; and
an attendant low degree of crystallinity or particle aggregation indicative of negligible POC-POC bonding.
