Two‐Dimensional Conjugated Metal–Organic Frameworks with a Ring‐in‐Ring Topology and High Electrical Conductance

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(26)

Опубликована: Апрель 16, 2024

Abstract Electrically conducting two‐dimensional (2D) metal–organic frameworks (MOFs) have garnered significant interest due to their remarkable structural tunability and outstanding electrical properties. However, the design synthesis of high‐performance materials face challenges limited availability specific ligands pore structures. In this study, we employed a novel highly branched D 3h symmetrical planar conjugated ligand, dodechydroxylhexabenzotrinaphthylene (DHHBTN) fabricate series 2D conductive MOFs, named M–DHHBTN (M=Co, Ni, Cu). This new family MOFs offers two distinct types pores, elevating complexity more advanced level. The intricate tessellation patterns are elucidated through comprehensive analyses involving powder X‐ray diffraction, theoretical simulations, high‐resolution transmission electron microscope. Optical‐pump terahertz‐probe spectroscopic measurements unveiled carrier mobility in DHHBTN‐based spanning from 0.69 3.10 cm 2 V −1 s . Among famility, Cu‐DHHBTN displayed high conductivity reaching 0.21 S at 298 K with thermal activation behavior. work leverages “branched conjugation” ligand encode heteroporosity into underscoring potential heterogeneous double‐pore structures for future applications.
