A FUNCTIONALIZED CYANINE HAVING A SILANE LINKER ARM, A METHOD OF PREPARING THEREOF AND USES THEREOF

摘要

A silane-modified cyanine of Formula (I) includes the valence tautomers thereof: wherein R1 is a linear, saturated or unsaturated alkyl chain, having 1 to 30 carbon atoms, wherein one or more carbon atoms are optionally substituted by a 4-, 5- or 6-membered aromatic or non aromatic cyclic grouping of carbon atoms; R8 and R9 are independently selected from the group consisting of—OCH3,—OCH2CH3,—OCH2CH2CH3,—OCH(CH3)2,—OCH2CH2OCH3,—Cl,—Br,—I, Formula (II), Formula (III),—N(CH3)2, Formula (IV), Formula (V), methyl, ethyl, propyl, isopropyl. The synthesis method and the use as a fluorescent marker are for inorganic solid supports, for example silica nanoparticles, and/or for biomolecules such as peptides, antibodies, DNA, RNA, etc.
