Pi-Conjugated Heavy-Metal Polymers Particularly Suited To Hydroponic Applications
US Patent:
2009031, Dec 24, 2009
Filed:
May 14, 2007
Appl. No.:
12/300424
Inventors:
Zeev Valentine Vardeny - Salt Lake City UT, US

Assignee:
University of Utah - Salt Lake City UT
International Classification:
A01G 1/00, C09K 11/06
US Classification:
47 581LS, 25230133
Abstract:
A class of organic light-emitting diodes (OLEDs) emit light tailored to the absorption spectra of growing plants. Upon photoexcitation, the OLEDs generate light in both the blue-green and red regions of the visible spectrum. A heavy metal atom present in the π-conjugated polymer chain (such as platinum and/or iridium) acts via the spin-orbit coupling mechanism to cause an enhancement of the ratio of fluorescent to phosphorescent emission to be of approximately equal strength. These two emission bands overlap the absorption spectra of common plants grown under hydroponic conditions.

Process For The Production Of Diaryl Iodonium Compounds
US Patent:
2005014, Jul 7, 2005
Filed:
Jan 7, 2004
Appl. No.:
10/753588
Inventors:
Leonard Wojcik - Holladay UT, US
David Cornell - Kingsport TN, US
David Cornell - Kingsport TN, US
International Classification:
C25B003/00
US Classification:
205413000
Abstract:
The present invention provides an electrochemical method for producing diaryl iodonium compounds wherein application of an electric current to an electrochemical cell containing a reaction mixture composed of a solvent, an iodoaryl compound and an electrolyte forms an oxidizing agent in situ. In this first step, the oxidizing agent is subsequently converted into a stable oxidized iodoaryl intermediate, typically an iodosyl compound. The electric potential is removed and in a second step a target aryl compound is introduced to the reaction mixture to react with the oxidized iodoaryl intermediate to form a diaryl iodonium compound.
