Introduction of various substitutions to the methine bridge of heptamethine cyanine dyes: Via substituted dianil linkers

The unique optical properties of cyanine dyes have prompted their use in numerous applications. Heptamethine cyanines are commonly modified on the methine bridge after synthesis of a meso-chlorine containing cyanine. Herein, a series of heptamethine cyanines containing modified methine bridges were synthesized using substituted dianil linkers. Their optical properties including, molar absorptivity, fluorescence, and quantum yield were measured as well as their hydrophobic effects in polar buffer solution. It was shown that dyes containing cyclopentene in the methine bridge or a phenyl ring in the meso position display increased molar absorptivity while the increased flexibility of the dye containing a cycloheptene in the methine bridge prevented fluorescence.

CHEMISTRY OF ENOL ETHERS. LX. AMINOFORMYLATION OF CYCLIC 1-ALKOXY-1,3-DIENES. SYNTHESIS OF PENTAMETHINE SALTS AND TRICARBOCYANINES WITH CYCLIC FRAGMENTS IN THE CONJUGATION CHAIN

The aminoformylation of cyclic 1-alkoxy-1,3-dienes by the Vilsmeier complex obtained from dimethylformamide and phosphorus oxychloride was investigated.The salts of the dianils of glutaconaldehyde derivatives with six-membered rings in the conjugation chain were synthesized by treatment of the reaction products with aniline in an acidic medium.They were used for the production of the corresponding tricarbocyanine dyes.
