Synthesis and electrochemical and photophysical studies of tetrathiafulvalene-annulated phthalocyanines.
The synthesis of tetrakis(tetrathiafulvalene)-annulated metal-free and metallophthalocyanines 5-8 via the tetramerization of the phthalonitrile derivative 4 is reported. All of them have been fully characterized by electronic absorption spectroscopy, thin-layer cyclic voltammetry, mass spectrometry, and elemental analysis. Their solution electrochemical data show two reversible four-electron ox...
متن کاملUnusual azobenzene/bipyridine palladacycles: structural, dynamical, photophysical and theoretical studies.
Two types of Pd(ii) azobenzene/bipyridine complexes with unusual coordination mode of azobenzenes, PdCl{(mu-Cl)(mu-R(1)C(6)H(3)N=NC(6)H(3)R(2))}Pd(bpy) 1a-4a and [(bpy)PdCl(mu-NH(2)C(6)H(3)N=NC(6)H(4))Pd(bpy)]Cl 3b were formed by the reaction of dicyclopalladated azobenzenes (DMF)PdCl(mu-R(1)C(6)H(3)N=NC(6)H(3)R(2))PdCl(DMF) with excess of bpy, where bpy=2,2'-bipyridine; R(2)=H and R(1)=H (1), ...
متن کاملStructural-functional studies of peptides derived from a long-chain snake neurotoxin Naja naja oxiana
Introduction: The design and structural characterization of mini-proteins with a compact, folded structure provide insight into the complex architecture of proteins today and has long been a challenging issue in structural- functional studies. Alpha neurotoxins from snake venom have a distinct folded structure comprised of a disulphide core and three loops or “fingers” each of these loops are c...
متن کاملSynthesis, characterization and photophysical studies of self-assembled azo biphenyl urea derivatives.
We reported the synthesis of a new series of azobiphenyl based urea derivatives 7 and their stimulus-responsive supramolecular structures in the form of sheet like self-assembled formations. The self-assembled nanostructural formations of azo derivatives 7 are strongly dependent on the nature of the solvent present in the systems. Further, we found that the amide hydrogen played a crucial role ...
متن کاملSynthesis and Photophysical Studies
In this study, three new fluorescein derivatives—5-bromo-4′,5′-dinitrofluorescein (BDNF), 5-bromo-4′,5′-diaminofluorescein (BDAF), and 5-bromo-4′,5′-bis(dimethylamino)fluorescein (BBDMAF)—were synthesized and their pH-dependent protolytic equilibria were investigated. In particular, BBDMAF exhibited pH-dependent fluorescence, showing strong emission only at pH 3–6. BBDMAF bears a bromine moiety...
