One of the most effective ways to tune electronic properties conjugated polymers is dope them with small-molecule oxidizing agents, creating holes on polymer and molecular anions. Undesirably, strong electrostatic attraction from anions dopants localizes created polymer, reducing their mobility. Here, a new strategy utilizing substituted boron cluster as dopant for employed. By designing have high redox potential steric protection core-localized electron density, highly delocalized polarons...
We recently reported the photophysical properties of boron dipyridylmethene (DIPYR) dyes, a class intensely fluorescent pyridine-based chromophores, which are structural analogues both acenes and BODIPYs. In this work, we endeavored to explore DIPYR dimers. The synthesis characterization two novel homoleptic meso-linked dimers bis-DIPYR bis-α-DIPYR, herein reported. Their structural, electrochemical, have been probed using steady-state time-resolved techniques including femtosecond...
Electron transfer across a mixed-valent hydrogen-bonded self-dimer of oxo-centered triruthenium clusters bridged by pair 4(3H)-pyrimidinones is reported. Spectroelectrochemical studies in methylene chloride reveal that 1 rapidly self-dimerizes upon one-electron reduction, forming the strongly coupled dimer (12)−. In state, significantly broadened, partially coalesced ν(CO) bands are observed, allowing estimation electron rate (kET) an optical Bloch line shape analysis. Simulation FTIR shapes...
Although bis(α-diimine)Ni complexes were prepared when amine-substituted chelates added to Ni(COD)2, the incorporation of strong-field phosphine donors allowed isolation (κ4-N,N,P,P-DI)Ni hydrosilylation catalysts. The crystallographic investigation two different compounds revealed that geometry about nickel influences observed degree α-diimine reduction.
Carboxylation of heteroarenes with CO<sub>2</sub>is achieved using alkali carbonate dispersed in mesoporous titania as a regenerable reagent.

The synthesis and characterization of four new Ni(II) bis(NHC) bipy complexes (bipy = 4, 4′-bipyridine, NHC N-heterocyclic carbene) are reported. These represent the first examples NiII(NHC2) L2 class compounds, where L is a two-electron-donor ligand. introduction double propyl bridged bis-NHC ligand (CProp2C) imparts reversibility to electrochemistry these complexes. electrochemical response includes two reductions, believed be based, bipy0/–, second metal based. unusual arrangements in...
It was recently discovered that (Ph2PPrPDI)Mn (PDI = pyridine diimine) exists as a superposition of low-spin Mn(II) is supported by PDI dianion and intermediate-spin antiferromagnetically coupled to triplet dianion, finding encouraged the synthesis electronic structure evaluation late first row metal variants feature same chelate.
