Alkoxy-Substituted Quadrupolar Fluorescent Dyes

Journal of the American Chemical Society, 2022
Polar and polarizable π-conjugated organic molecules containing push-pull chromophores have been investigated extensively in the past. Identifying unique backbones and building blocks for fluorescent dyes is a timely exercise. Here, we report the synthesis and characterization of a series of fluorescent dyes containing quadrupolar A-D-A constitutions ...

Terrylenimides: New NIR Fluorescent Dyes

Chemistry – A European Journal, 1997
AbstractTerrylenimides 3 and 4 represent a new class of blue colorants, exhibiting absorption maxima at 650 to 700 nm and fluorescence emissions in the NIR region (673 to 750 nm). The terrylenimides were synthesized by means of various organometallic coupling reactions, catalyzed by transition metal complexes (Nio, Pdo) and starting from the aromatic ...

Axially Chiral Bichromophoric Fluorescent Dyes

The Journal of Organic Chemistry, 2011
A new life for Kurt Mislow's authentic amines: Diaminobiphenyls were applied as the framework materials for the synthesis of axially chiral bichromophoric systems with strong CD and CPL effects.

Lissamine FF Fluorescent Dye

Journal of Environmental Engineering, 1983
The use of Rhodamine WT fluorescent dye in the presence of nitrite was recently linked with the formation of diethylnitrosamine (DENA), a compound with mutagenic and carcinogenic properties. Lissamine FF fluorescent dye was selected as a substitute for Rhodamine WT dye to avoid potential problems upstream of water intakes.

NLOphoric imidazole-fused fluorescent anthraquinone dyes

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2021
The Z-scan and DFT techniques were explored to investigate the non-linear optical properties of anthraquinone fused imidazole-based D-π-A dyes. With the help of UV-visible spectral analysis, pH study, CV analysis, HOMO-LUMO interaction, MEP plots, and quinoidal character the influence of intramolecular charge transfer characteristics and H-bonding ...

Fiberized fluorescent dye microtubes

SPIE Proceedings, 2013
In the present work we study the effect of the length of fluorescent dye-filled micro-capillaries on the fluorescence spectra. Two types of micro-capillaries have been studied: a 100 μm inner diameter fused silica capillary with a transparent coating and one of the holes of a fiber optic glass ferrule with 125 μm inner diameter. The tubes were filled

Endocytosis Assays Using Cleavable Fluorescent Dyes

2022
Endocytosis mediates the entry of surface and extracellular cargoes into the cell. In this chapter, we describe assays to quantitively measure the endocytosis of both soluble and transmembrane cargo proteins, taking advantage of cleavable fluorescent dyes labeling cargo proteins or antibodies recognizing cargo proteins.

Lucifer dyes—highly fluorescent dyes for biological tracing

Nature, 1981
Lucifer dyes are intensity fluorescent 4-aminonaphthalimides which are readily visible in living cells at concentrations and levels of illumination at which they are nontoxic. Because of their low molecular weight they frequently pass from one cell to another; this widespread phenomenon, termed dye-coupling, is thought to reveal functional ...

Fluorescent Voltage-Sensitive Dyes

Journal of Clinical Neurophysiology, 1988
Voltage-sensitive dyes are a means to optically monitor changes in membrane potential. Their application in research has grown steadily over the last two decades as better dyes have been developed. The techniques presently in use are providing unique information about biologic systems from bacteria to the functional organization of primate occipital ...
