Abstract:
1. An article comprising: a nanoscopic pathway having a conductivity; an insulating dielectric surrounding the nanoscopic pathway; and a nanoscopic switch in electronic communication with the nanoscopic pathway being capable of altering the conductivity of the nanoscopic pathway, wherein the nanoscopic pathway comprises a conducting polymer, wherein the conducting polymer has a structure comprising the formula: wherein A and C are aromatic groups; B and D can be a heteroatom or metal and chosen from a group of N, P, S, As, Se, or —CC-M-CC-(M=FeL x , RuL x , PdL x , PtL x , CoL x , RhL x , where L is neutral (phosphine, nitrogen, or π-arene based ligand) or charged (nitrogen, oxygen, or charged π-arene ligand), or are selected from the group consisting of a carbon-carbon double bond and a carbon-carbon triple bond; and any hydrogen on aromatic group A and C can be replaced by E and F respectively, wherein a and b are integers which can be the same or different and a=0–4, b=0–4 such that when a=0, b is nonzero and when b=0, a is nonzero, and at least one of E and F includes a bicyclic ring system having aromatic or non-aromatic groups optionally interrupted by O, S, NR 1 and CR 1 2 wherein R 1 is selected from the group consisting of hydrogen, C 1 –C 20 alkyl, C 1 –C 20 alkoxy and aryl and n is less than about 10,000, and wherein, when E or F is not said bicyclic ring system, E or F is a part of aromatic group A or C.
