The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Silver(I) trifluoromethanesulfonate( cas:2923-28-6 ) is researched.Electric Literature of CAgF3O3S.Han, Jingqi; Cheng, Shun-Cheung; Yiu, Shek-Man; Tse, Man-Kit; Ko, Chi-Chiu published the article 《Luminescent monomeric and dimeric Ru(II) acyclic carbene complexes as selective sensors for NH3/amine vapor and humidity》 about this compound( cas:2923-28-6 ) in Chemical Science. Keywords: ruthenium acyclic carbene ammonia amine vapor humidity sensor. Let’s learn more about this compound (cas:2923-28-6).
A new class of luminescent bis(bipyridyl) Ru(II) pyridyl acyclic carbene complexes with environmentally-sensitive dimerization equilibrium have been developed. Owing to the involvement of the orbitals of the diaminocarbene ligand in the emissive excited state, the phosphorescence properties of these complexes are strongly affected by H-bonding interactions with various H-bonding donor/acceptor mols. With the remarkable differences in the emission properties of the monomer, dimer, and H-bonded amine adducts together with the change of the dimerization equilibrium, these complexes can be used as luminescent gas sensors for humidity, ammonia, and amine vapors. With the responses to amines and humidity and the corresponding change in the luminescence properties, a proof-of-principle for binary optical data storage with a reversible concealment process has been described.
