Patent ID: 8173630

Claim:
A composition comprising an array of electrodes, a plurality of said electrodes each comprising a redox-active molecule selected from the group consisting of a porphyrinic macrocycle, a sandwich compound of the formula L 1 -M-L 2 or the formula L 1 -M 1 -L 2 -M 2 -L 3 where M, M 1 , and M 2 are independently selected metals and L 1 , L 2 , and L 3 are independently selected porphyrins or porphyrinic macrocycles, and a metallocene, wherein said redox-active molecule is attached to the electrode by a polypodal tether wherein said polypodal tether is a 2-podal, 3-podal, 4-podal, or 5-podal tether, the legs of said tether do not contain a benzene and each leg of said tether contains at least one carbon and not more than 10 carbons.
