|Issue Date:||25-Jul-2012||Citation:||Chen, W., Bay, W.P., Wong, M.W., Huang, D. (2012-07-25). Selenium Blue-α and -β: Turning on the fluorescence of a pyrenyl fluorophore via oxidative cleavage of the Se-C bond by reactive oxygen species. Tetrahedron Letters 53 (30) : 3843-3846. ScholarBank@NUS Repository. https://doi.org/10.1016/j.tetlet.2012.05.022||Abstract:||Rapid oxidation of nonfluorescent pyrenyl-CH 2SeAr (Ar = o-nitrophenyl) by hypochlorite yielded pyrenyl-CH 2Cl and pyrenyl-CH 2OH and turns on blue fluorescence, while slow oxidation of pyrenyl-CH 2SeAr with excess H 2O 2 leads to pyrenyl-CHO which emits a bluish-green fluorescence. The homolog, pyrenyl-CH 2CH 2SeAr′ (Ar′ = o-nitrophenyl) reacts slower with H 2O 2 and ClO - giving the same product, vinyl pyrene. © 2012 Elsevier Ltd.
