Reaction of [FeCl(dppe)Cp*] with [Mo(C≡CC6H4-4-C≡CH)(dppe)(η-C7H7)], 1, and NaBPh4 in methanol gives the alkynylvinylidene complex [{Fe(dppe)Cp*}{μ-C≡CC6H4(H)C═C}{Mo(dppe)(η-C7H7)}]BPh4, [2A]BPh4, which is deprotonated to form heterobimetallic, 1,4-diethynylbenzene-bridged [{Fe(dppe)Cp*}(μ-C≡CC6H4C≡C){Mo(dppe)(η-C7H7)}], 3. The compound [2A]BPh4 exists as major component an equilibrium mixture [Fe(dppe)Cp*}{μ-C═C(H)C6H4C≡C}{Mo(dppe)(η-C7H7)}]BPh4, [2B]BPh4, formed a consequence proton...
Abstract The linear optical (LO) and nonlinear (NLO) properties of a series isocyanurates functionalized by donor arms at the periphery are reported herein. These octupolar derivatives were obtained in straightforward way from commercial isocyanate fully characterized. Although several these compounds known, those that exhibited largest NLO activities all new compounds. In terms second‐order activity, exhibit remarkable activity/transparency tradeoffs. third‐order longer with stronger groups...
Abstract Transition‐metal complexes containing stimuli‐responsive systems are attractive for applications in optical devices, photonic memory, photosensing, as well luminescence imaging. Amongst them, photochromic metal offer the possibility of combining specific properties centre and response group. The synthesis, electrochemical photophysical characterisation a series donor–acceptor azobenzene derivatives that possess bipyridine groups connected to 4‐dialkylaminoazobenzene moiety through...
We report a combined theoretical and experimental study of both the structural optical properties phosphorescent cyclometalated square-planar (phenylbipyridyl)platinum(II) acetylide complexes, namely (Pt(tBu2-ĈN̂N)(C≡C-Ph)] (Pt(hex2-ĈN̂N)(C≡C-thienyl)] that exhibit, at high concentrations, an additional emission band longer wavelength. The geometry optimizations ground lowest triplet excited states considered monomers different possible dimers have been performed in solution using several...
The theoretical investigation of the physico-chemical properties pyrazolooxazine derivatives, which could exhibit anti-inflammatory activity, has been carried out using DFT computations at B3LYP/6-311[Formula: see text]G (d, p) level. It appears that both pyrazolooxazin-2-one (1) and pyrazolooxazin-2-thione (2) thermal stability whereas electron donating character latter is higher than former species. Molecular electrostatic potential surfaces (MESP) have used in order to determine activity...
The synthesis of new 2-pyrone-based hydrazones has been prepared by the coupling 6-methyl-2H-furo[3,2-c]pyran-3,4-dione with diazonium salts, obtained diazotization aniline derivatives. structure all compounds was established spectroscopic methods, and more stable conformer theoretically confirmed potential energy profile analysis. hydrazone dyes were acetylated both groups showed moderate to good radical scavenging activity.
Abstract The mechanism of protonation aminopyrones and the nature protonated forms are some interest because biological importance these compounds. use CNDO/2 molecular electrostatic potentials contour maps shows that most reactive centre is extracyclic oxygen. MNDO energies confirm this atom elucidate basicity nitrogen atom. effect a N substitution on 13 has been studied. calculations in agreement with preliminary experimental results.
