Sublimation kinetics of scandium β-diketonates

The volatile scandium-β-diketonates are synthesised using acetylacetone (acac) and tetramethylheptanedione (tmhd) as coordinative ligands for CVD application. The X-ray powder patterns are indexed and analysed and found to be orthorhombic and monoclinic p

Photoinduced energy- and electron-transfer processes within dynamic self-assembled donor-acceptor arrays

The synthesis and the photophysical properties of a series of noncovalently assembled donor-acceptor systems, dyads, is reported. The presented approach uses an "innocent" coordination compound, a scandium(III) acetyl acetonate derivative, as core and promotor of the dyad formation. Intercomponent photoinduced energy transfer or electron transfer within the dynamic assembly, which yields to a statistical library of donor-acceptor systems, is reported. The assemblies for energy-transfer processes are constituted by an energy donor, Ru(bpy)32+-based component (bpy = 2,2′-bipyridine), and by an energy-acceptor moiety, anthracene-based unit, both substituted with a chelating ligand, acetyl acetone, that via coordination with a scandium ion will ensure the formation of the dyad. If N,N,N′N′-tetramethyl-2,5-diaminobenzyl-substituted acetyl acetonate ligands are used in the place of 9-acyl-anthracene, intramolecular photoinduced electron transfer from the amino derivative (electron donor) to the Ru(bpy)32+-unit was detected upon self-assembly, mediated by the scandium complex. The photophysical processes can be studied on the lifetime of the kinetically labile complexes.

Rate and mechanism of ligand exchange of tris(acetylacetonato)scandium(III) in acetonitrile

Tris(acetylaceotnato)scandium(III) undergoes ligand exchange with the enolate form of acetylacetone in CD3CN at 30-74°C. The observed first-order rate constant, obtained by the 1H NMR method, is expressed by k0 = k1′[enol] + k2′ at [complex] ? 0.05 M, [Hacac] = 0.19 - 0.58 M, and [H2O] = 0.026-0.26 M; k1′ = 52 ± 3 M-1' s-1 and k2′ = 1.5 ± 0.9 s-1 at 56°C. No water catalysis was observed. The k2′ term is minor in the concentration region. The ΔH? and ΔS? values for k1′ are 36 ± 5 kJ mol-1 and -105 ± 16 J K-1 mol-1, respectively. The deuterium isotope effect k1′(H)/k1′(D) was significant (ca. 5). The Ia mechanism is assigned to the rate-determining formation of an intermediate containing a one-ended acac- and a unidentate Hacac in the enol form.
