Latest Patents

One of her latest patents is the Vapochromic photodiode. This device is a sandwich-type, organic p-n junction photodiode prepared by electrode-positioning an insoluble layer of oligomerized tris(4-(2-thienyl)phenyl)amine onto conducting indium-tin oxide coated glass. The process involves spin-coating a stacked platinum compound, bis(cyanide)-bis(para-dodecylphenylisocyanide)platinum (II), from chloroform onto the oligomer layer. Following this, the platinum complex is coated with a micro-array of aluminum electrodes through vapor deposition. This innovative device demonstrates rectification of current and produces a measurable photocurrent. The photocurrent action spectrum aligns with the absorption spectrum of the platinum complex. Changes in the action spectrum with layer thickness indicate that a p-n junction is formed at the interface of the molecular layers, serving as the site of rectification. Notably, exposure to acetone vapor causes a dramatic shift in the action spectrum to longer wavelengths, while exposure to chloroform vapor returns it to the original spectrum. These findings showcase a new type of photosensor capable of reporting the arrival of organic vapors.
