Patent ID: 7288679

Claim:
A device comprising at least one organophosphonium divalent transition metal dye wherein said organophosphonium transition metal dye is an organophosphonium compound according to the general formula (I) wherein M is Co or Ni, wherein n≧1, m≧1, Σ(+)≧1, and wherein −2n=mΣ(+), and wherein R 1 , R 2 , R 3 and R 4 are the same or different and each represent an alkyl group, an aliphatic group, an alicyclic hydrocarbon group, an aromatic group, a heteroaromatic group, a hyperbranched polymer group, a dendrimeric group or R 1 , R 2 , R 3 and R 4 each independently represents the necessary atoms to form a ring system with one another, and wherein L 1 , L 2 , L 3 and L 4 each independently represents one of F, Cl, Br and I, and when m=1, then Σ(+)=2n and consequently 2n positively charged centers are present in the phosphonium cation, and when n=1 and Σ(+)=1, then m=2 and consequently two phosphonium cations (P + R 1 R 2 R 3 R 4 ) and (P + R 5 R 6 R 7 R 8 ) are present in the molecule, wherein R 5 , R 6 , R 7 , R 8 are the same or different and each represents an alkyl group, an aliphatic group, an alicyclic hydrocarbon group, an aromatic group, a heteroaromatic group, a hyperbranched polymer group, a dendrimeric group or R 5 , R 6 , R 7 and R 8 each independently represents the necessary atoms to form a ring system with one another wherein said device is selected from the group consisting of a scanner, a digitizer, a display and a photosensitive device.
