The intramolecular capture of thermally generated merocyanine dyes derived from naphthopyrans: Photochromism of 5-(diarylhydroxymethyl)-2H-naphtho[1,2-b]pyrans

Synthesis, Structure/Spectra Correlation and Chromism Studies of some Novel Monomethine and bis-Monomethine Cyanine Dyes

“…Cyanine dyes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] were and still have been the central focus of scientists in a several fields such as chemistry, biology, physics, biotechnology, engineering, pharmacology and medicine. This is due to their multi-purpose using and applications in a diverse and a broad area.…”

Synthesis and Photosensitization Evaluation of Some Novel Polyheterocyclic Cyanine Dyes

“…Cyanine dyes [1][2][3][4][5][6][7][8][9][10][11][12][13][14] are a class of organic heterocyclic dyes, which have long captured the interest of the scientific community. This is because the class of cyanine dyes has proved to be particularly useful in a diverse and a broad area of science, technology and engineering.…”

“…Their uses and applications includes but not limited to color and non color (black and white) photography, in high energy laser and digital image storage, analytical reagents over a wide range of pH of media, indicators for solvent polarity, in biological and biomedical use as molecular probes and as fluorescent dyes commonly used for DNA visualization assays. In addition, cyanine dyes [15][16][17][18][19][20][21][22][23][24][25][26][27][28] are widely used as optical recording materials, thermal writing display, laser printers, laser filters, absorptivity and antimicrobial efficiency, for probing lipophilic environments, halophobic pockets of enzymes and components of supramolecular structures.…”

A Simple Levulinate-based Ratiometric Fluorescent Probe for Sulfite with a Large Emission Shift

“…[12][13][14] In addition, the colorimetric technique possesses a great advantage over other analytical methods because it has the capability to detect sulfite by the naked-eye, without the aid of any advanced instruments. [28][29][30][31][32][33][34] Thus, novel colorimetric and ratiometric fluorescent probes for sulfite with a large emission shift have become our target.…”
