1. A catalytic carbon capture material comprising:
a microporous polymer including a Tröger's base moiety, wherein the microporous polymer is formed of: (i) one of 2,6-diaminotoluene or spirobi[fluorene] diamine precursors; and ii) dimethoxymethane precursors; and
a transition metal coordinated within the microporous polymer;
wherein the catalytic carbon capture material selectively captures carbon dioxide (CO2) and also is a catalyst that simultaneously converts the captured carbon dioxide into one or more carbon dioxide-based products.
