Abstract: A sandwich device was prepared by electrodeposition of an insoluble layer of oligomerized tris(4-(2-thienyl)phenyl)amine onto conducting indium-tin oxide coated glass, spin coating the stacked platinum compound, tetrakis(p-decylphenylisocyano)platinum tetranitroplatinate, from toluene onto the oligomer layer, and then coating the platinum complex with aluminum by vapor deposition. This device showed rectification of current and gave electroluminescence. The electroluminescence spectrum (&lgr;max=545 nm) corresponded to the photoluminescence spectrum of the platinum complex. Exposure of the device to acetone vapor caused the electroemission to shift to 575 nm. Exposure to toluene vapor caused a return to the original spectrum. These results demonstrate a new type of sensor that reports the arrival of organic vapors with an electroluminescent signal.

Abstract: A sandwich-type, organic p-n junction photodiode is prepared by electrode-position of an insoluble layer of oligomerized tris(4-(2-thienyl)phenyl)amine onto conducting indium-tin oxide coated glass, spin-coating the stacked platinum compound, bis(cyanide)-bis(para-dodecylphenylisocyanide)platinum (II), from chloroform onto the oligomer layer, and then coating the platinum complex with a micro-array of aluminum electrodes by vapor deposition. This device shows rectification of current and gives a measurable photocurrent. The photocurrent action spectrum follows the absorption spectrum of the platinum complex; changes in the action spectrum with layer thickness point to a p-n junction formed at the interface of the molecular layers as the site of rectification. Exposure of the device to acetone vapor causes the action spectrum to shift dramatically to longer wavelength. Exposure to chloroform vapor causes a return to the original spectrum.

Abstract: An electrically conductive polymer is comprised of the reaction product of a dendrimer and an electrophoric compound which exhibits .pi.-stacking upon reduction. The reaction product which is a peripherally modified dendrimer is formed and reduced, either chemically or electrochemically, in a polar solvent. The reduced electrophoric moieties aggregate (form .pi.-stacks) to form electrically conductive pathways. The reduced peripherally modified dendrimers of the invention can be cast into films and other solid forms to provide flexible electrical conductors and semiconductors. The conductive polymers of the invention exhibit electrical conductivities comparable to that of doped polyacetalene, but are oxygen and moisture stable.
