Abstract Designing highly conducting metal–organic frameworks (MOFs) is currently a subject of great interest for their potential applications in diverse areas encompassing energy storage and generation. Herein, strategic design which metal–sulfur plane integrated within MOF to achieve high electrical conductivity, successfully demonstrated.

Light-emitting diodes (LEDs) have drawn tremendous potential as a replacement of traditional lighting due to its low-power consumption and longer lifetime. Nowadays, the practical white LEDs (WLED) are contingent on photon down-conversion phosphors containing rare-earth elements, which limits utility, energy, cost efficiency. In order resolve energy crisis address environmental concerns, designing direct WLED is highly desirable remains challenging issue. To circumvent existing difficulties,...
The self-assembly of a three-dimensional strontium-based metal–organic framework [Sr(Hbtc)(H2O)]n (1) was achieved through the reaction Sr(NO3)2 with 1,2,4-benzenetricarboxylic acid (1,2,4-H3btc) ligand under hydrothermal conditions. This Sr-based exhibits remarkable semiconducting behavior, as evidenced by theoretical calculations and experimental measurements. Temperature-dependent DC conductivity, near-room-temperature AC diffuse reflection spectra, photoluminescence spectra provide...
Abstract Metal‐organic frameworks (MOFs) have recently emerged as attractive materials for their tunable properties, which been utilized diverse applications including sensors, gas storage, and drug delivery. However, the high porosity poor electrical conductivity of MOFs restrict optoelectronic applications. Owing to inherent tunability, a broadband photon absorbing MOF can be designed. Combining superior properties along with ultrahigh carrier mobility graphene, first time, this study...
