A porous Sm(iii) coordination nanotube with hydrophobic and hydrophilic channels

摘要

The π-π stacking interactions between tptz units from adjacent Sm(tptz)(HCOO)_3 coordination nanotubes leads to additional 1D channels (tptz = 2,4,6-tris(2-pyridyl)-s-triazine). The present compound is a rare case of a tubular porous material with both hydrophobic and hydrophilic channels. Permanent porosity was confirmed by N_2 adsorption isotherms.
