In 2018,Klein, Eugen; Heymann, Leonard; Hungria, Ana B.; Lesyuk, Rostyslav; Klinke, Christian published 《Colloidal lead iodide nanorings》.Nanoscale published the findings.Application of 624-73-7 The information in the text is summarized as follows:
Colloidal chem. of nanomaterials experienced a tremendous development in the last decades. In the course of the journey 0D nanoparticles, 1D nanowires, and 2D nanosheets have been synthesized. They have in common to possess a simple topol. We present a colloidal synthesis strategy for lead iodide nanorings, with a non-trivial topol. First, two-dimensional structures were synthesized in nonanoic acid as the sole solvent. Subsequently, they underwent an etching process in the presence of trioctylphosphine, which determines the size of the hole in the ring structure. We propose a mechanism for the formation of lead iodide nanosheets which also explains the etching of the two-dimensional structures starting from the inside, leading to nanorings. In addition, we demonstrate a possible application of the as-prepared nanorings in photodetectors. These devices are characterized by a fast response, high gain values, and a linear relation between photocurrent and incident light power intensity over a large range. The synthesis approach allows for inexpensive large-scale production of nanorings with tunable properties. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diiodoethane(cas: 624-73-7Application of 624-73-7)
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Application of 624-73-7
