A series of H2O and/or EtOH soluble, self-assembling quaternary ammonium salts containing a dansyl (DNS) fluorescent moiety suitable for attachment to both porous ([DNS-NH-(CH2)3-NMe2-R+][X–] (2); R = -Si(OMe)3, X– = Cl–) and non-porous (3a); R = -PO(OEt)2, 3b; -PO(Oi-Pr)2, 3c; -(PO(OH)2, X– = Br–), 4; [DNS-NH-(CH2)3-NMe2-(CH2)3-NH(CH2PO(OEt)2)2+][Br–], 5; R = -((CH2)3SCOCH3, X– = Cl–), 6a; (R = -(CH2)nO(C6H4)CO(C6H5), n = 3, X– = Br–, 6b; n = 3, X– = Cl–, 6c; n = 3, X– = I–, 6d; n = 4, X– = Br–, 6e; n = 4, X– = I–, 6f; n = 6, X– = Br–, 6g; n = 6, X– = Cl–, 6h; n = 6, X– = I–), 7; (R = -CH2-CH:CH2, X– = Br–) surfaces were prepared from the precursor dansyl amine (1; DNS-NH-(CH2)3-NMe2). Compounds 1-7 were characterized by NMR (1H, 13C, 29Si (2), 31P (3a-c, 4)) spectroscopy, HRMS, UV-Vis and fluorescence spectroscopy. Addnl. characterization of compounds 1 and 7 were carried out by X-ray structure determinations Phys. attachment of compound 2 to cotton surfaces after immersion in solutions containing fluorescent dyes was verified by exposure to UV light and by complexation with bromo-phenol blue that rendered the surfaces visibly blue in color. Phosphorus containing dansyl fluorescent dye, 3c, was attached to a stainless steel surface by exposure to an aqueous solution containing this dye, resulting in the formation of a self-assembled fluorescent monolayer. UV cure of plastic surfaces (polypropylene, silicon medical tubing) coated with compound 6a resulted in the covalent attachment of the dyes. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Related Products of 6294-17-3).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Related Products of 6294-17-3
