Water-Soluble Rylene Dyes as High-Performance Colorants for the Staining of Cells

Water-Soluble Rylene Dyes as High-Performance Colorants for the Staining of Cells. Weil, Tanja; Abdalla, Moustafa A.; Jatzke, Claudia; Hengstler, Jan; Muellen, Klaus (Max-Planck-Institut fuer Polymerforschung, Mainz 55128, Germany). Biomacromolecules, 6(1), 68-79 (English) 2005 American Chemical Society. CODEN: BOMAF6. ISSN: 1525-7797. DOCUMENT TYPE: Journal CA Section: 9 (Biochemical Methods) Section cross-reference(s): 14, 80 The synthesis of perylene and terrylene chromophores carrying a single poly(ethylene oxide) chain is presented. 695152-67-1 and 73183-34-3 which are cas registry numbers of chemicals are mentioned. These chromophores reveal a strong solvatochromic behavior: High fluorescence in nonpolar solvents and weak fluorescence in polar solvents which is mainly attributed to aggregation. Therefore, such chromophores are attractive candidates as sensitive fluorescent probes reflecting the polarity of their environment. In particular, their suitability for the staining of cellular membranes is presented in detail. .

PRIORITY: JP 2005-223152 1 Aug 2005. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 73 This invention pertains to a method for producing Sym-triindole derivs. I [wherein R1-R5 = independently H, F, alkyl, etc.; R6 = alkyl, alkoxyalkyl, arylalkyl, or haloalkyl] which has excellent film-forming properties. Even when used to form a single-layer org. EL element, the deriv. luminesces. It is hence widely applicable to the field of org. EL materials, etc., and is esp. suitable for use in an org. EL element. For example, the compd. I (where R1=R2=R4=R5=H; R3=t-Bu, R6=2-ethylhexyl) was prepd. in a multi-step synthesis. .
