Synthesis and optical properties of cyanine dyes with an aromatic azonia skeleton
Six cyanine dyes with an aromatic azonia skeleton (1a-f) were obtained by the reaction of chlorinated heptamethylene cyanine and 2-aminopyridine derivatives. Five of them (1a-d and 1f) emit red and near-infrared fluorescence at 600-800 nm. The fluorescent stains of living cells indicate that they ca...

Summary: | Six cyanine dyes with an aromatic azonia skeleton (1a-f) were obtained by the reaction of chlorinated heptamethylene cyanine and 2-aminopyridine derivatives. Five of them (1a-d and 1f) emit red and near-infrared fluorescence at 600-800 nm. The fluorescent stains of living cells indicate that they can penetrate the cell membrane, especially the hydroxyl-substituted dye (1c), it has lysosome targeting ability. |
