The title of the article was 《cis/trans-Isomeric Cation Tuning Photoluminescence and Photodetection in 2D Perovskites》.Application of 27489-62-9 The author mentioned the following in the article:
Cationic components in the organic-inorganic hybrid perovskites (OIHPs) play an important role in the arrangement and tilting of the inorganic part that is responsible for semiconducting, luminescent, and photoelectronic properties. Herein, we report two 2D OIHP compounds, (cis-4ACHO)2(H3OBr)PbBr4 (1) and (trans-4ACHO)2(H3OCl)PbBr4 (2) (4ACHO = 4-aminocyclohexanol), showing both photoluminescence (PL) and photodetection (PD) that are tuned by the cis- and trans configurational isomerism of 4ACHO. Crystals of 1 and 2 exhibit similar packing structures but with different crystallog. symmetries. Compound 2 displays a broadband white-light emission with a higher PL efficiency (6.6%) than 1 (2.1%) that emits narrow band blue light while the PD property of 1 is better than 2 with a higher on/off ratio under the same conditions. The PL and PD of the two compounds show a seesaw relationship, which provides a new perspective for understanding the PL and PD properties in OIHPs. The experimental process involved the reaction of trans-4-Aminocyclohexanol(cas: 27489-62-9Application of 27489-62-9)
trans-4-Aminocyclohexanol(cas: 27489-62-9) belongs to anime. The methylamines occur in small amounts in some plants. Many polyfunctional amines (i.e., those having other functional groups in the molecule) occur as alkaloids in plants—for example, mescaline, 2-(3,4,5-trimethoxyphenyl)ethylamine; the cyclic amines nicotine, atropine, morphine, and cocaine; and the quaternary salt choline, N-(2-hydroxyethyl)trimethylammonium chloride, which is present in nerve synapses and in plant and animal cells.Application of 27489-62-9
