Rational crystal engineering of conductive metal-organic frameworks for promising electrochemical energy storage.

ABSTRACT: 3D conductive metal-organic frameworks (c-MOFs) have emerged as a promising candidate for advancing energy storage due to excellent inherent electrical conductivity, efficient ion diffusion through open channels and high-density active sites. However, the facile preparation of 3D c-MOFs remains a great challenge. In this study, we developed two new 3D nitrogen-rich Ni-based c-MOFs (Ni-BPE and Ni-BPA) via the reaction of Ni²⁺ ions, 2-(3,5-dicarboxyphenyl)-6-carboxybenzimidazole (H₃L) and 1,2-di(4-pyridyl) ethylene dipyridyl (BPE) or 1,2-di(pyridin-4-yl) ethyne (BPA). The nitrogen-rich ligands, featuring pyridyl and benzimidazole units, extend the π-conjugation system, contributing to the high conductivity of Ni-BPE. Furthermore, compared to flexible BPE with a c
