Cyanine dyes possessing carboxylic acid groups have been used in many different fields of
study. The acid groups can act as handles for bioconjugation or as metal chelators. Several …

The unique optical properties of cyanine dyes have prompted their use in numerous
applications. Heptamethine cyanines are commonly modified on the methine bridge after …

New unsymmetrical pentamethine cyanine dyes containing two non-equivalent reactive
groups selected from carboxyl, amino and hydroxyl in different combinations were …

The effect of varying short-chain alkyl substitution of the indole nitrogens on the
spectroscopic properties of cyanine dyes was examined. Molar absorptivities and …

A series of symmetric pentamethine cyanine dyes derived from various N-substituted
benzothiazolium/benzoselenazolium salts, and a conjugated bis-aniline derivative …

Carbocyanine dyes are a class of organic compounds that contain two heterocycles that act
as electron donors and acceptors connected by a conjugated methine bridge. Herein the …

Asymmetric monomethine cyanines have been extensively used as probes for nucleic acids
among other biological systems. Herein we report the synthesis of seven monomethine …

Six new double N-alkylated dimethine cyanine dyes were synthesized and the crystal
structures of two of the dyes were analyzed by X-ray diffraction. The investigation of the …

New cyanines were prepared by an efficient and practical route with satisfactory overall yield
from low-cost starting materials. The photophysical behavior of the cyanines was …

New polymethine cyanine dyes covering heptamethine cyanine dyes (tricarbocyanine dyes)
and nonamethine cyanine dyes (tetracarbocyanine dyes) derived from the nucleus benzo …
