Effective Na+ fluorescent sensing by new podand-type receptor connecting two pyrene units and diphenyl ether was written by Nishimura, Yukihiro;Takemura, Tetsuo;Arai, Sadao. And the article was included in ARKIVOC (Gainesville, FL, United States) in 2009.Reference of 80480-15-5 The following contents are mentioned in the article:
A new podand-type receptor for Na+ detection was synthesized by connecting two 1-pyrenecarbonylmethyl groups with two hydroxy groups of 2,2′-dihydroxydiphenyl ether. With the addition of Na+ at 20-200 μM, the increasing monomer emission (423 nm) and the decreasing excimer emission (524 nm) of pyrene were observed In contrast with the receptor, the fluorescence spectra of the corresponding compound obtained from 2,2′-dihydroxydiphenylmethane are only slightly affected by the addition of Na+. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Reference of 80480-15-5).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Reference of 80480-15-5
