A highly permeable porous organic cage composite membrane for gas separation

Abstract

We proposed a facile porous organic cage (POC) composite membrane fabricated with the RCC3 cage crosslinked by terephthaloyl chloride for CO 2 /N 2 and CH 4 /N 2 separation. The amine-rich subnanochannel provided by RCC3 promoted the rapid penetration of CO 2 .
