A triazole compound has shown electrocatalytic activity for CO2 reduction into CH4 and CO. Combining both CO2 capture and reduction in a single molecular system is an attractive approach. In this case, a molecule can be used to capture CO2 in one redox state and function as an electrocatalyst for reduction at a second redox state. Scheme 1. The chemical structure of 2,1,3-benzothiadiazole 4,7-dicarbonitrile Recently, a compound called 2,1,3-benzothiadiazole (BT) has been shown to bind two CO2 molecules upon reduction at ca. -1.9 V vs Fc 0 / + in a two-electron process. In previous work from our group, a similar molecule called 2,1,3-benzothiadiazole-4,7-dicarbonitrile (BTDN, scheme 1) was shown to bind with protons and upon subsequent reduction, carry on catalytic hydrogen evolution. Due to the two strongly electron-withdrawing nitrile groups, it is much easier to reduce BTDN in comparison to the mother compound BT. The first reduction of BTDN is achieved at -1.06 V vs Fc 0/+ and the second reduction at -1.89 V vs Fc 0/+ . For comparison, the first reduction of BT is found at -1.87 V vs Fc 0/+ . This encouraged us to further study the interaction between BTDN at its different reduced states and CO2 as well as to explore the potential catalytic ability for CO2 reduction in this work.
