Bis(2-iodothiophen-3-yl)methanone (cas: 474416-61-0) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Electric Literature of C9H4I2OS2

Electrochemistry and Near-infrared Electrochromism of Electropolymerized Polydithiophenes with β, β‘-Positions Bridged by Carbonyl or Dicarbonyl Substitute was written by Liu, Wei;Gu, Chuantao;Wang, Jiuxing;Sun, Mingliang;Yang, Renqiang. And the article was included in Electrochimica Acta in 2014.Electric Literature of C9H4I2OS2 This article mentions the following:

The β, β’-positions carbonyl or dicarbonyl bridged dithiophenes were prepared and electrochem. polymerized into corresponding polymers, polycyclopenta[2,1-b;3,4-b’]dithiophen-4-one (PCDK) or polybenzo[1,2-b:6,5-b’]dithiophene-4,5-dione (PCD2K), in B trifluoride di-Et etherate based electrolyte. Potentiostatic and potentiodynamic methods confirmed that the PCDK and PCD2K films can be successfully electrodeposited in high quality with comparable intermol. spacings at âˆ?.1 Å-3.2 Å. The mass changes and ion transport of the two polymers during redox processes were studied by electrochem. quartz crystal microbalance and in situ spectroelectrochem. methods, to study the formation of the two polymers. In situ UV-visible spectroscopy evidenced the PCDK and PCD2K evolved into polarons in the near IR region under applied potentials. Electrochromic behaviors showed that the PCDK film appeared reddish brown in neutral state and cyan or green in oxidized state while the PCD2K showed green to dark green from neutral to oxidized states. Potential switching between oxidized and neutral states of the two films revealed that maxima transmittance changes were 38.23% and 36.64% for the PCDK and PCD2K. Thermal degradation of the two polymers showed their robust stability that allows for the application in a wide temperature scale. In the experiment, the researchers used many compounds, for example, Bis(2-iodothiophen-3-yl)methanone (cas: 474416-61-0Electric Literature of C9H4I2OS2).
