Uncommon quadruple stacking topology in a honeycomb-sheet MOF compatible with through-space conduction†
Abstract
Quadruple stacking topology with an unusual threefold stacking periodicity in four honeycomb sheets was realized in a flexible wavy honeycomb-sheet MOF (PMC-20). The infinite π-stacked arrays, formed exclusively at the π-conjugated core of the linker site, contribute to the highest electrical conductivity among the reported naphthalenediimide (NDI)-based crystals.
