Mn₂(2,5-disulfhydrylbenzene-1,4-dicarboxylate): A Microporous Metal–Organic Framework with Infinite (−Mn–S−)_∞ Chains and High Intrinsic Charge Mobility

The reaction of MnCl₂ with 2,5-disulfhydrylbenzene-1,4-dicarboxylic acid (H₄DSBDC), in which the phenol groups in 2,5-dihydroxybenzene-1,4-dicarboxylic acid (H₄DOBDC) have been replaced by thiophenol units, led to the isolation of Mn₂(DSBDC), a thiolated analogue of the M₂(DOBDC) series of metal–organic frameworks (MOFs). The sulfur atoms participate in infinite one-dimensional Mn–S chains, and Mn₂(DSBDC) shows a high surface area and high charge mobility similar to that found in some of the most common organic semiconductors. The synthetic approach to Mn₂(DSBDC) and its excellent electronic properties provide a blueprint for a potentially rich area of exploration in microporous conductive MOFs with low-dimensional charge transport pathways

High Charge Mobility in a Tetrathiafulvalene-Based Microporous Metal–Organic Framework

The tetratopic ligand tetrathiafulvalene-tetrabenzoate (H₄TTFTB) is used to synthesize Zn₂(TTFTB), a new metal–organic framework that contains columnar stacks of tetrathiafulvalene and benzoate-lined infinite one-dimensional channels. The new MOF remains porous upon desolvation and exhibits charge mobility commensurate with some of the best organic semiconductors, confirmed by flash-photolysis-time-resolved microwave conductivity measurements. Zn₂(TTFTB) represents the first example of a permanently porous MOF with high charge mobility and may inspire further exploration of the electronic properties of these materials
