In some cases, the catalyzed mechanism may include additional steps.In a article, 1640-39-7, molcular formula is C11H13N, introducing its new discovery. COA of Formula: C11H13N

Here we report that the difficulties encountered in the synthesis of a dual-pendant sulfonate bis(indolenine)squaraine dye can be overcome through the use of equimolar amounts of the common reaction catalyst, thus creating an organic salt between the sulfonate groups and the protonated catalyst. Thus, a range of water-soluble dyes can further be prepared, by simply altering the catalyst. Crystal structures of four subsequent derivatives, prepared in this manner, are reported and show that, although the squaraine moieties remain essentially planar, the packing lattices can vary significantly, and the expectation that both sulfonic acid groups will protonate a stoichiometric amount of the available organic base catalyst is also demonstrated by one structure to not be fully true. Two of the dyes, whose crystal structures are reported, proved to be suitable as colorimetric stains for protein separation in sodium dodecylsulphate polyacrylamide gel electrophoresis (SDS-PAGE), and an optimal method for staining is reported. Results obtained for a fifth dye, crystal structure not obtained, are also reported. In all cases the results were compared against non-colloidal Coomassie Brilliant Blue (CBB) and it was found that the limit of detection for all squaraine derivatives examined were comparable with that of CBB although the resolution between protein bands was better. In addition, it was discovered that gels stained with the fifth dye (presented in this study) could be imaged in UV excitation/fluorescent imaging mode. The image robustness (or colour fastness) of all squaraines was found to be good for only a few hours.

A number of photochromic indolinospirochromenes that contain an octadecyl substituent in the 1 position were synthesized.The introduction of an octadecyl group in place of a methyl group increases the stability of the merocyanine form in solution but does not change its spectral characteristics.On the other hand, the introduction of phenyl groups in place of methyl groups in the 3 position does not change the stability of merocyanine but gives rise to a bathochromic shift of the long-wave absorption band.

Polarity-sensitive fluorogenic dyes raised considerable attention because they can turn on their fluorescence after binding to biological targets, allowing background-free imaging. However, their brightness is limited, and they do not operate in the far-red region. Here, we present a new concept of fluorogenic dye based on a squaraine dimer that unfolds on changing environment from aqueous to organic and thus turns on its fluorescence. In aqueous media, all three newly synthesized dimers displayed a short wavelength band characteristic of an H-aggregate that was practically nonfluorescent, whereas in organic media, they displayed a strong fluorescence similar to that of the squaraine monomer. For the best dimer, which contained a pegylated squaraine core, we obtained a very high turn-on response (organic vs aqueous) up to 82-fold. Time-resolved studies confirmed the presence of nonfluorescent intramolecular H-aggregates that increased with the water content. To apply these fluorogenic dimers for targeted imaging, we grafted them to carbetocin, a ligand of the oxytocin G protein-coupled receptor. A strong receptor-specific signal was observed for all three conjugates at nanomolar concentrations. The probe derived from the core-pegylated squaraine showed the highest specificity to the target receptor together with minimal nonspecific binding to serum and lipid membranes. The obtained dimers can be considered as the brightest polarity-sensitive fluorogenic molecules reported to date, having ?660,000 M-1 cm-1 extinction coefficient and up to 40% quantum yield, whereas far-red operation region enables both in vitro and in vivo applications. The proposed concept can be extended to other dye families and other membrane receptors, opening the route to new ultrabright fluorogenic dyes.

The dramatically different DNA-binding properties of the two isomeric forms of a photochromic spiropyran have been demonstrated, enabling photoswitched DNA binding. The closed, UV-absorbing form shows no signs of interaction with DNA. Upon UV exposure the spiropyran is isomerized to the open form that binds to DNA by intercalation. The process is fully reversible as the corresponding dissociation process is induced by visible light. Copyright

Self-assembling nanoparticles of amphiphilic polymers can transport hydrophobic molecules across hydrophilic media and, as a result, can be valuable delivery vehicles for a diversity of biomedical applications. Strategies to monitor their dynamics noninvasively and in real time are, therefore, essential to investigate their translocation within soft matrices and, possibly, rationalize the mechanisms responsible for their diffusion in biological media. In this context, we designed molecular guests with photoactivatable fluorescence for these supramolecular hosts and demonstrated that the activation of the fluorescent cargo, under optical control, permits the tracking of the nanocarrier translocation across hydrogel matrices with the sequential acquisition of fluorescence images. In addition, the mild illumination conditions sufficient to implement these operating principles permit fluorescence activation within developing Drosophila melanogaster embryos and enable the monitoring of the loaded nanocarriers for long periods of time with no cytotoxic effects and no noticeable influence on embryogenesis. These photoresponsive compounds combine a borondipyrromethene (BODIPY) chromophore and a photocleavable oxazine within their covalent skeleton. Under illumination at an appropriate activation wavelength, the oxazine ring cleaves irreversibly to bring the adjacent BODIPY fragment in conjugation with an indole heterocycle. This structural transformation shifts bathochromically the BODIPY absorption and permits the selective excitation of the photochemical product with concomitant fluorescence. In fact, these operating principles allow the photoactivation of BODIPY fluorescence with large brightness and infinite contrast. Thus, our innovative structural design translates into activatable fluorophores with excellent photochemical and photophysical properties as well as provides access to a general mechanism for the real-time tracking of supramolecular nanocarriers in hydrophilic matrices.
