Solid state self-assembly of triptycene-based catechol derivatives by multiple OH⋯O hydrogen bonds

Single crystals of two triptycene-based catechol derivatives 1 and 2 were obtained, and their X-ray crystal structural studies showed that the two tecton molecules had different conformations in the solid state, and they could self-assemble into interesting 3D networks with solvent molecules included inside, in which multiple OH⋯O hydrogen bonds played important roles.
