Three-fold interpenetrating three-dimensional networks based on C-methylcalix[4]resorcinarene incorporating benzophenone guest molecules

A new solid based on C-methylcalix[4] resorcinarene and the linker molecule bis(4-pyridylmethylidyne) hydrazine (bpmh) has been prepared, in which brick-wall sheets are linked in the third dimension to give networks with three intersecting perpendicular channels; the networks interpenetrate threefold, but nevertheless leave cavities capable of including sizable guest molecules.
