The compounds trans-M2(TiPB)2(L) 2 and trans-M2(TiPB)2(L′) 2 have been prepared from the reactions between M2(T iPB)4 (TiPB = 2,4,6-triisopropylbenzoate, M = Mo or W) and LH or L′H (～2 equiv.), respectively, where L = O 2CC(CN)CH-C6H4-NPh2 and L′ = O2CC(CN)CH-C4H3S-C6H 4-NPh2. These cyanoacrylate ligands promote intense M 2δ to L or L′ π*-transitions that span the range 550-1100 nm. The two molybdenum complexes have been characterized by single crystal X-ray studies that reveal the extensive L-M2-L or L′-M2-L′ M2δ-ligand π-conjugation. The new compounds have been characterized by electronic structure calculations employing density functional theory (DFT) and time-dependent-DFT, cyclic voltammetry, electronic absorption and steady state emission spectroscopy and femtosecond (fs) and nanosecond (ns) time resolved transient absorption (TA) and fs time-resolved infrared spectroscopy (TRIR). The latter allows the determination of the S1 states as 1MLCT that are delocalized over both L and L′. For molybdenum the T1 states are 3MoMoδδ* whereas for tungsten they are 3MLCT.

Five metal-free organic dyes (DIA1-DIA5) based on rigid triarylamine donors have been synthesized and their photophysical/electrochemical properties, theoretical calculations and dye-sensitized solar cell (DSSC) performances have been investigated. All th

We developed an iterative synthetic method for oligo-aryl compounds using an organosilicon-based palladium-catalyzed cross-coupling reaction. Aryl compounds containing a benzyloxy(diisopropyl)silyl group (masked Si group) had sufficient chemical stability, and the unmasking step proceeded in a high yield under mild conditions. Both of the key unmasking/coupling steps required no strict anhydrous or degassed conditions. The developed procedure was used for the synthesis of thiophene-based organic dyes for dye-sensitized solar cells.
