An active energy ray curable composition includes a copolymer and a photo-acid generator, the copolymer being obtained by reacting a cocondensate with a polymerizable unsaturated monomer, wherein the cocondensate is obtained by hydrolyzing and condensing a first silane compound having a hydrolyzable silyl group and a second silane compound having a hydrolyzable silyl group, the cocondensate has 0.1 to 3.0 polymerizable unsaturated groups per molecule, the first silane compound is represented by the general formula (I): R.sup.1(SiR.sup.2.sub.a(OR.sup.3).sub.3-a), and the second silane compound is represented by the general formula (II): R.sup.4(SiR.sup.2.sub.a(OR.sup.3).sub.3-a)).

Described herein are facile, one-step initiated plasma enhanced chemical vapor deposition (iPECVD) methods of synthesizing hyper-thin (e.g., sub-100 nm) and flexible metal organic covalent network (MOCN) layers. As an example, the MOCN may be made from zinc tetraphenylporphyrin (ZnTPP) building units. When deposited on a membrane support, the MOCN layers demonstrate gas separation exceeding the upper bounds for multiple gas pairs while reducing the flux as compared to the support alone.
