Abstract

Porous coordination polymer (PCP) with 2,7-bis(4-pyridyl)-[1]benzothieno[3,2-b][1]benzothiophene (BTBT-4py) ligands was synthesized. The PCP provides both pores and infinite π-stacked columns via the assemblies of linear coordination polymers. The overlap integrals between highest occupied molecular orbitals (HOMOs) of adjacent ligands largely depend on the conformation of BTBT cores. The PCP also showed drastic structural change induced by desolvation. This approach to introduce porosity in organic semiconductor crystal can lead to the development of molecular-based devices, such as porous field-effect transistor.
