“…After systematic optimizations of the synthetic conditions, the M-DABDT CPs were synthesized through a solvent thermal method by keeping the mixture of DABDT with M(OAC) 2 in water/iso-propanol or N , N -dimethylformamide (DMF) at 120 °C for 48 h, which were different from the reported conventional solution process. ,− The products from water/iso-propanol were named as M-DABDT-1, while those from DMF were named as M-DABDT-2, and all of the products were obtained as black powders with moderate yields. The Fourier transform infrared (FT-IR) spectra (Figure S1) of the products were in good agreement with the literature, , indicating the successful preparations of M-DABDT CPs.…”

“…Compared with the well-explored MOFs, the simplest coordination polymers (CPs), one-dimensional (1D) CPs, were less explored. , Although 1D CPs with high electrical conductivity based on S-donor ligands were discovered in the 1980s − (Scheme ), only a few investigations on their potential applications as electronic materials − were performed. In particular, Kim et al reported 1D CPs based on NPM and 2,5-diamino-1,4-benzenedithiol (DABDT) and assumed the M-S 2 N 2 centers in these CPs could coordinate with oxygen. ,, This inspired us to utilize M-DABDT CPs as ORR catalysts with M-S 2 N 2 catalytic centers .

Conductive materials involving nonprecious metal coordination complexes as electrocatalysts for the oxygen reduction reaction (ORR) have received increasing attention in recent years. Herein, we reported efficient ORR electrocatalysts containing M-S 2 N 2 sites with tunable selectivity based on simple one-dimensional (1D) coordination polymers (CPs). The 1D CPs were synthesized from M(OAc) 2 and 2,5-diamino-1,4benzenedithiol (DABDT) by a solvent thermal method. Due to their good electrical conductivities (10 −6 −10 −2 S cm −1 ), the 1D CPs could be used as ORR catalysts in low catalytic amounts without the addition of carbon materials. Cobalt-based CPs showed a well-organized structure of nanosheets with Co-S 2 N 2 sites exposed and exhibited remarkable electrocatalytic ORR activity (E onset = 0.93 V vs reversible hydrogen electrode (RHE), E 1/2 = 0.82 V, n = 3.85, J L = 5.22 mA cm −2 , Tafel slope of 63 mV dec −1 ) in alkaline media. However, nickel-based CPs favored a 2e − ORR process with ∼87% H 2 O 2 selectivity and an E onset of 0.78 V. This work provides new opportunities for the construction of ORR catalysts based on conductive nonprecious metal CPs.

“…The Co−DABDT is selected further for the study of its electronic capabilities due to its high electrical conductivity at room temperature under ambient conditions (Figure 1c). 34,35 Figure 2a shows the synthesis process of a freestanding Co− DABDT thin film via an interfacial reaction, 26 where the 2D coordination film self-assembles at the interface between the aqueous and organic phases. The prepared planar film is thin (Figure S1a), and the stacked layers get thicker as the reaction time increases (Figure 2b).…”

Two-dimensional (2D) metal–molecule hybrid frameworks have attracted great attention due to their π–d interactions for the charge–spin–lattice coupling, promising for next-generation molecular electronics. However, a high electrical conductivity is indispensable to realize such potential. Herein, we design and assemble a conductive 2D conjugated coordination thin film through an interfacial reaction between the aqueous and organic phases. Its electronic conducting properties are derived from the π–d coupling interactions to achieve an electrical conductivity of 1.05 S/cm, while the stimulus-dependent π–d interactions induce multifunctional sensory capabilities. The Co–DABDT (DABDT = 2,5-diamino-1,4-benzenedithiol dihydrochloride) thin films demonstrate an excellent performance for sensing light, strain, temperature, and humidity, as well as robust mechanical stability. The 2D frameworks with multisensing properties for real-time static and dynamic monitoring are promising for smart wearable electronic systems.

“…1, 2). Given the potential of [P,S] chelate chemistry [1], such binucleating ligands should be interesting building blocks for the formation of bimetallic complexes and polymetallic arrays, especially since the [N,S] structural analog of 2, 2,5-diamino-1,4-benzenedithiol has been used for the syntheses of polymeric transition metal complexes [18,19]. Initial coordination studies show that compound 2 acts as an effective binucleating ligand, as ascertained through the formation of the bimetallic bis(iron tricarbonyl) complex ( Fig.…”
