Synthesis, structure, spectral properties and DFT quantum chemical calculations of 4-aminoazobenzene dyes. Effect of intramolecular hydrogen bonding on photoisomerization

In this paper three different “push-pull” 4-aminoazobenzene dyes have been synthesized in order to characterize their photochromic behavior in different solvents. The molecular geometry was optimized by DFT/B3LYP functional combined with the standard 6–31

Thermodynamic study for the stability of aromatic complexes formation derived from the reaction of 4-dimethyl amino benzaldehyde with diazotized dinitro aniline reagents

This research includes the preparation of aromatic azoimine complexes resulting from the coupling reaction (4) of Schiff bases with diazotized dinitroaniline reagent. Ultraviolet spectra, infrared spectra, and melting points are among the most important p

Design, synthesis and biological evaluation of small-azo-dyes as potent Vesicular Glutamate Transporters inhibitors

Vesicular Glutamate Transporters (VGLUTs) allow the loading of presynapic glutamate vesicles and thus play a critical role in glutamatergic synaptic transmission. VGLUTs have proved to be involved in several major neuropathologies and directly correlated to clinical dementia in Alzheimer and Parkinson's disease. Accordingly VGLUT represent a key biological target or biomarker for neuropathology treatment or diagnostic. Yet, despite the pivotal role of VGLUTs, their pharmacology appears quite limited. Known competitive inhibitors are restricted to some dyes as Trypan Blue (TB) and glutamate mimics. This lack of pharmacological tools has heavily hampered VGLUT investigations. Here we report a rapid access to small molecules that combine benefits of TB and dicarboxylic quinolines (DCQs). Their ability to block vesicular glutamate uptake was evaluated. Several compounds displayed low micromolar inhibitory potency when size related compounds are thirty to forty times less potent (i.e. DCQ). We then confirmed the VGLUT selectivity by measuring the effect of the series on vesicular monoamine transport and on metabotropic glutamate receptor activity. These inhibitors are synthesized in only two steps and count among the best pharmacological tools for VGLUTs studies.

Synthesis and characterization of novel yellow azo dyes from 2-morpholin-4-yl-1,3-thiazol-4(5H)-one and study of their azo-hydrazone tautomerism

Novel yellow azo dyes were synthesized by diazotization of aromatic amines followed by coupling with 2-morpholin-4-yl-1,3-thiazol-4(5H)-one and fully characterized. The geometries of the synthesized dyes for azo and hydrazone tautomeric forms were optimized using B3LYP, CAM-B3LYP and M06 functional and 6-31G(d) and 6-311++G (d,p) basis sets, also their electronic excitation properties were evaluated using density functional theory. The optimized geometries reveal that the hydrazone for is more stable than the azo form. Photophysical properties of the synthesized dyes were evaluated by UV-Visible spectroscopy and compared with computed vertical excitation obtained from TDDFT. The results clearly illustrate existence of dye 8a, 8b and 8c in hydrazone tautomeric form, while 8d exist in both azo as well as hydrazone form. Thermal stabilities were estimated by using thermo gravimetric analysis, and results revels that the synthesized dyes have good thermal stability.

Synthesis and properties of some novel pyrazolone-based heterocyclic azo disperse dyes containing a fluorosulfonyl group

A series of heteroarylazo disperse dyes derived from pyrazolones and fluorosulfonyl anilines were synthesized, and their thermal and spectral properties were investigated with respect to the effect of substituents on absorption spectra, halochromism, and

NLO properties of poled azocarbazole-epoxy composites

Azocarbazole dyes are organic molecules that have already shown potential in nonlinear optical applications in host-guest systems. These molecules should be covalently bound to a host polymer network. This can be easily achieved if the host polymer is an

The rate of the acid cleavage of the Z-E-isomeric 1-aryl-3-- and 1-aryl-3--triazenes 1 - 5 is investigated in dependence on the substituents in the aryl and benzo residue.The Z-isomer
