Metallo-organic ensembles of tritopic subphthalocyanine ligands

Enhanced open-circuit voltage in subphthalocyanine/C60 organic photovoltaic cells.

A double-heterostructure boron subphthalocyanine chloride (SubPc)/C60 thin-film photovoltaic cell exhibits a more than doubled Voc compared to a conventional copper phthalocyanine (CuPc)/C60 cell under 1 sun AM1.5G simulated illumination. The lower oxidation potential of SubPc results in an increase in the energy difference between the lowest unoccupied molecular orbital of the acceptor-like ma...

Dithiolene complexes as metallo-ligands: a crown-ether approach

Paramagnetic dithiolene complexes as metallo-ligands: ether/thioether coordination.

The secondary coordination ability of a paramagnetic nickel dithiolene complex, bearing an ether coordinating function within a nine-membered flexible ring, has been demonstrated in its [NiCl(DMF)(2)](+) complex, through coordination by both ether and thioether functions, allowing for a ferromagnetic interaction between both paramagnetic entities.

Efficient Organic Photovoltaic Cells Based on Nanocrystalline Mixtures of Boron Subphthalocyanine Chloride and C60

The electrical and structural behavior of uniformly mixed films of boron subphthalocyanine chloride (SubPc) and C60 and their performance in organic photovoltaic cells is explored. Device performance shows a strong dependence on active-layer donor–acceptor composition, and peak efficiency is realized at 80 wt.% C60. The origin of this C60-rich optimum composition is elucidated in terms of morph...

Control of magnetic properties in metallo-organic thin films

Magnetic metallo-organic thin films have been prepared at different growth temperatures to characterize the influence of structural properties on the magnetic characteristics. A quantitative analysis of the grain size shows that the growth temperature increases the elliptical grain size considerably. Long grains of planar iron phthalocyanine form quasi one-dimensional iron chains, which are emb...
