Synthesis, characterization, and UV–visible study of some new photochromic formyl-containing 1′,3′,3′-trimethylspiro[chromene-2,2′-indoline] derivatives

The spiropyran derivatives can exist in two forms, the closed-ring spiropyran form and the open-ring merocyanine (MC) form. The SP form could be converted into the MC form upon UV irradiation. In this work, some 1′,3′,3′-trimethylspiro[chromene-2,2′-indoline] derivatives containing the nitro and formyl groups are synthesized via the reaction of 1,3,3-trimethyl-2-methylene-5-nitroindoline with the corresponding salicylaldehyde derivatives. These compounds have different photochromic behaviors. The synthesized photochromic molecules are characterized by the FT-IR, 1H-NMR, and 13C-NMR spectroscopic techniques. In order to investigate the photochromic properties of these compounds, the UV–visible spectroscopic analyses of their methanolic solutions before and after exposure to a UV lamp (in the spectral range of 360–400?nm) are studied.

ACTIVATABLE FLUOROGENIC COMPOUNDS AND USES THEREOF AS NEAR INFRARED PROBES

Novel fluorogenic compounds designed such that upon a chemical event, compounds capable of emitting NIR light are generated, are disclosed. The compounds comprise two or more acceptor-containing moieties and a cleavable donor-containing moiety, being in c

donor-two-acceptor dye design: A distinct gateway to NIR fluorescence

The detection of chemical or biological analytes upon molecular reactions relies increasingly on fluorescence methods, and there is a demand for more sensitive, more specific, and more versatile fluorescent molecules. We have designed long wavelength fluorogenic probes with a turn-ON mechanism based on a donor-two-acceptor π-electron system that can undergo an internal charge transfer to form new fluorochromes with longer π-electron systems. Several latent donors and multiple acceptor molecules were incorporated into the probe modular structure to generate versatile dye compounds. This new library of dyes had fluorescence emission in the near-infrared (NIR) region. Computational studies reproduced the observed experimental trends well and suggest factors responsible for high fluorescence of the donor-two-acceptor active form and the low fluorescence observed from the latent form. Confocal images of HeLa cells indicate a lysosomal penetration pathway of a selected dye. The ability of these dyes to emit NIR fluorescence through a turn-ON activation mechanism makes them promising candidate probes for in vivo imaging applications.

Photochromic and thermochromic properties of diimines of 2,6-diformylphenoles

Electronic spectra, photochromic and thermochromic properties of a series of di(N-alkyl and N-arylimine)-4-R-2,6-diformyIphenols in solutions and in solid phase were investigated. The effect on the above properties of electronic characteristics of substit
