1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Quality Control of 1,2-Diiodoethane

Quality Control of 1,2-DiiodoethaneIn 2022 ,《Structural Reconstruction in Lead-Free Two-Dimensional Tin Iodide Perovskites Leading to High Quantum Yield Emission》 appeared in ACS Energy Letters. The author of the article were Ghimire, Sushant; Oldenburg, Kevin; Bartling, Stephan; Lesyuk, Rostyslav; Klinke, Christian. The article conveys some information:

The authors report a structural reconstruction-induced high photoluminescence quantum yield of 25% in colloidal 2-dimensional Sn iodide nanosheets that are synthesized by a hot-injection method. The as-synthesized red-colored nanosheets of octylammonium Sn iodide perovskites at room temperature transform to white hexagonal nanosheets upon washing or exposure to light. This structural change increases the bandgap from 2.0 to 3.0 eV, inducing a large Stokes shift and a broadband emission. Further, a long photoluminescence lifetime of ∼1 μs is measured for the nanosheets. Such long-lived broad and intense photoluminescence with a large Stokes shift is anticipated to originate from Sn iodide clusters that are formed during the structural reconstruction. The stereoactive 5s2 lone pair of Sn(II) ions perturbs the excited state geometry of the white hexagonal nanosheets and facilitates the formation of self-trapped excitons. Such broadband and intensely emitting metal halide nanosheets are promising for white light-emitting diodes. The experimental part of the paper was very detailed, including the reaction process of 1,2-Diiodoethane(cas: 624-73-7Quality Control of 1,2-Diiodoethane)
