Synthesis and properties of new electrochromic derivatives of 3-aryl-4,5-bis(pyridin-4-yl)oxazole

A series of new electrochromic derivatives of 3-aryl-4,5-bis(pyridin-4-yl)isoxazole was synthesized. Their electrochemical characteristics were studied by cyclic voltammetry, and a low eff ect of the substituents in the isoxazole and pyridinium cycles on the positions of the oxidation and reduction peaks was shown. The electrochromic cells prepared on the basis of the synthesized compounds were reversibly colored into brown upon the application of a voltage of 1.5 V. The spectral properties of the synthesized compounds under the electric field application and their stability for cycling from 0 to 2 V were studied.

Organometallic π-tweezers incorporating pyrazine- and pyridine-based bridging units

The synthesis of heterobimetallic (TiCu, TiAg) and tetranuclear heterobimetallic (Ti2Ag2) transition metal complexes based on the organometallic π-tweezer building blocks [Ti](CCSiMe 3)2 is described. In [{[Ti](μ-σ,π-CCSiMe 3)2}M-LL]+ and [{[Ti](μ-σ,π- CCSiMe3)2}MLLM{(Me3SiCC-μ-σ,π) 2[Ti]}]2+ (M = Cu, Ag; LL = pyrazine- or pyridine-based bridging units) the metal containing parts are spanned by π-conjugated organic bridges LL. Depending on the nature of LL coordination polymers are also accessible. Pyrazine- and pyridine-based π-conjugated σ-donor molecules, such as 4,4′-bipyridine, 1,2-di(4-pyridyl)ethylene, 3,5-dipyridyl-1,2,4-triazole, N,N′-bis(4-pyridylmethylidene)benzene-1,4- diamine, 2,5-di(pyridylmethylidene)cyclopentanone, 2,6-di(4-pyridylmethylidene) cyclohexanone (LL, 2a-2g) can successfully be used to span heterobimetallic π-tweezer units of the type [{[Ti](μ-σ,π-CCSiMe3) 2}M]+ ([Ti] = (η5-C5H 4SiMe3)2Ti; M = Cu, Ag). The thus accessible di-cationic species [{[Ti](μ-σ,π-CCSiMe3) 2}MLLM{(Me3SiCC-μ-σ,π)2[Ti]}] 2+ (4), which are formed via the formation of [{[Ti](μ-σ, π-CCSiMe3)2}MLL]+ (3) complexes, can be isolated in yields between 66% and 99%. However, when C5H 4NCHCHC6H4CHCHNC5H4 (5a) and C5H4NCHNC6H4CHCHNC 5H4 (5b), respectively, are reacted with {[Ti](μ-σ,π-CCSiMe3)2}AgBF4(1c) in a 1:1 molar ratio, then the silver(I) ion is released from the organometallic π-tweezer 1c and coordination polymers [AgBF4 ? 5a] n (6a) and [AgBF4 ? 5b]n (6b) along with [Ti](CCSiMe3)2 (7) are formed in quantitative yield.

Oxidative coupling of methylpyridines

The conversion of methylpyridines on melted and solid-state alkaline catalysts was studied over the temperature range 430-720°C. It was shown that melted catalysts are preferable for use in the oxidative coupling of methylpyridines. The melt NaOH + 10 wt% V2O5 turned out to be the most selective catalyst in the dimerization reaction of methylpyridines.

Laser Flash Photolysis of trans-1,2-Bis(4-pyridyl)ethylene in Aqueous Solution

Reactions of trans-1,2-bis(4-pyridyl)ethylene (neutral form: M) and its conjugate acids, HM+ and H2M2+, following excitation by laser pulses, were studied in aqueous solution.The initial photoreaction of M (at pH > 7, λexc = 248 nm) is photoionization in a one quantum process, thereby forming the radical cation (λmax = 325 nm, lifetime 80 ns) and the hydrated electron (e-aq) in low quantum yield (0.01).The H adduct radical (HM., λmax = 455 nm) is formed by addition of e-aq to M followed by protonation with water, as in pulse radiolysis.HM. and its conjugate acid (H2M.+, λmax = 500 nm) are in equilibrium with pKa = 9.8 in buffered solution.H2M.+ is also formed (in low yield) via biphotonic photoionization of HM+ at pH 4-5 and of H2M2+ at pH 2+ the photohydroxide (H2M+OH, λmax = 400 nm) was observed.H2M+OH is the only transient in neat aqueous solution, when photoionization does not occur (λexc = 308 nm) and decays by protonation (rate constant 7 x 107 dm3 mol-1 s-) to give the photohydrate, as is supported by time-resolved conductivity measurements.In 2-propanol/water (1:9 and 1:1, λexc = 248 or 308 nm) HM. or H2M.+, depending on pH, are mainly formed by H-atom abstraction from the alcohol involving the 1(n,?*) states of M and HM+.Excited H2M2+, however, yields H2M+OH, as it does in the absence of 2-propanol.
