In 2019,Chemistry – A European Journal included an article by Werr, Marco; Kaifer, Elisabeth; Wadepohl, Hubert; Himmel, Hans-Joerg. Name: 2-Chloro-1H-benzo[d]imidazole. The article was titled 《Tuneable Redox Chemistry and Electrochromism of Persistent Symmetric and Asymmetric Azine Radical Cations》. The information in the text is summarized as follows:
Mol. organic radicals have been intensively studied in the last decades, due to their interesting optical, magnetic and redox properties. Here we report the synthesis and characterization of persistent organic radicals from one-electron oxidation of redox-active azines (RAAs), composed of two guanidinyl or related groups. By connecting two different groups together, asym. compounds result. In this way a series of compounds with varying redox potential is obtained that could be oxidized reversibly to the mono- and the dicationic charge states. The accessible redox states were fully determined by chem. redox reactions. The standard Gibbs free energy change for disproportionation of the radical monocation into the dication and the neutral mol. in solution, estimated from cyclovoltammetric measurements, varies between 43 and 71 kJ mol-1. While the neutral RAAs absorb predominately UV light, the radical monocations display strong absorptions covering almost the entire visible region and extending for some compounds into the NIR region. A detailed anal. of this highly reversible electrochromism is presented, and the fast switching characteristics are demonstrated in an electrochromic test device. In the experiment, the researchers used many compounds, for example, 2-Chloro-1H-benzo[d]imidazole(cas: 4857-06-1Name: 2-Chloro-1H-benzo[d]imidazole)
2-Chloro-1H-benzo[d]imidazole(cas: 4857-06-1) binds to monoclonal antibodies, inhibiting their binding to their corresponding antigens. This activity may be due to its ability to bind covalently with amino groups on proteins and other molecules.Name: 2-Chloro-1H-benzo[d]imidazole
