Noncovalent π-stacked robust topological organic framework

Significance A robust noncovalent π∙∙∙π interaction-stacked organic framework (OF), called πOF, consisting of a permanent three-dimensional porous structure that is held together by pure intralayer noncovalent π∙∙∙π interactions is synthesized and characterized. πOF shows excellent thermostability and high recyclability and exhibits self-healing properties by which the parent porosity is recovered upon solvent annealing at room temperature. We demonstrate remarkable transport properties of πOF in an organic-field-effect transistor, with mobility that is superior to traditional covalent OFs. πOF is a porous and conductive material for high-performance organic electronics.
