Li, Longdi published the artcileRoom temperature phosphorescence properties of 6-coumarinsulfonyl chloride, HPLC of Formula: 10543-42-7, the publication is Fenxi Huaxue (1992), 20(11), 1257-60, database is CAplus.
6-Coumarinsulfonyl chloride (C6SCl) was used as the fluorescence and low-temperature phosphorescence labeling reagent for amino acids. In this paper, the room-temperature phosphorescence (RPT) of C6SCl on the several solid substrates, such as filter paper, polyamide films, microcrystalline cellulose, cellulose nitrate, and silica gel for chromatog. etc. was induced successfully by selection of the heavy atom perturbers and exptl. conditions. The RTP emission of C6SCl has high selectivity, only divalent lead salts are efficient perturber among the examined fifteen compounds and the Pb(OAc)2 induced the most strong RTP signal. Using 1.0 mol/L Pb(OAc)2 as the perturber and filter paper as the solid substrate, more intensive RTP signal with high signal to blank ratio was obtained. The RTP signal intensity (λx/λm = 320/496 nm) as a function of the amount of C6SCl has a good linear relationship in 0.2 μL sample solution containing 4 to 200 pmol. These results mean that C6SCl, a new developing luminescence-labeling compound, can be expected to serve as not only a fluorescence labeling reagent, but also a RTP one.
