A route to functionalised pores in coordination polymers via mixed phosphonate and amino-triazole linkers

摘要

The ability to control size, shape and functionality of pores in materials is of fundamental importance to understanding sorption (host-guest) phenomena. We present a coordination polymer compound with narrow pores lined by free amine functionalities. Cu(aminotriazole)(1,4-dihydrogenphosphonate)hydrate, 1, forms a pillared layered structure where alternating pillaring units are replaced by the N-heterocycle to generate the pores. Single-crystal and powder X-ray diffraction data are presented as well as the thermogravimetric analysis and CO2, N2 and H2 gas sorption analyses.
