1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene

Triarylboron-based fluorescent conjugated microporous polymers was written by Liu, Xiaoming;Zhang, Yuwei;Li, He;A, Sigen;Xia, Hong;Mu, Ying. And the article was included in RSC Advances in 2013.Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene This article mentions the following:

Novel triarylboron-based conjugated microporous polymers (BCMPs) were successfully synthesized and characterized, which are insoluble in common organic solvents and water, and can keep stable up to 310 °C under a nitrogen atm. According to the nitrogen physisorption isotherms, the Brunauer-Emmett-Teller sp. surface area values for these porous materials vary between 815 and 911 m2 g-1. Two polymer frameworks display good carbon dioxide uptake capacity at 273 K and 1 bar. These materials might find applications in organic electronics and sensing technologies. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene).
