Fabrication of conjugated microporous polytriazine nanotubes and nanospheres for highly selective CO2 capture.

A one-spot template approach for fabricating porous organic nanotubes was developed and a molecular design, i.e. introducing thiophene and s-triazine functionalities to enhance host-guest interactions, lead to novel porous solids with high capacities for CO2 and exceptionally high ideal selectivities over N2 for effective gas storage and separation.
