Patent number: 6362914Abstract: Electrochromic devices and materials having enhanced daylight stability are described. The materials have a redox center linked to an energy receptor site that may serve to dissipate excited state energy from the redox center, alternatively the receptor site may absorb harmful radiation prior to the absorption by the redox center.Type: GrantFiled: February 27, 2001Date of Patent: March 26, 2002Assignee: Gentex CorporationInventors: Kelvin L. Baumann, Thomas F. Guarr, David A. Theiste

Publication number: 20010007904Abstract: A process for synthesizing 2-amino-5-dimethlyaminophenyl thiosulfonic acid comprises the step of oxidizing N,N′-dimethyl-&rgr;-phenylene-diamine in the presence of a source of thiosulfate ions, while maintaining the temperature of the reaction mixture not higher than about 10° C. This compound is useful as an intermediate in the synthesis of toluidine blue O.Type: ApplicationFiled: January 11, 2001Publication date: July 12, 2001Inventor: Douglas D. Burkett

Patent number: 6242602Abstract: Dihydrophenazines and bis(dihydrophenazines) are prepared in high yield under commercially viable reaction conditions by reacting a catechol with a 1,2-diaminoaryl compound, wherein either the catechol or the 1,2-diaminoaryl compound is provided in at least 50% molar stoichiometric excess. The product may be oxidized to the corresponding phenazine, but is preferably derivatized at one or both of the 5,10-positions to form a monosubstituted or disubstituted dihydrophenazine or bis(dihydrophenazine). Most preferably, 5,10-dialkyl-5,10-dihydrophenazines are prepared starting from catechol and 1,2-diaminoaryl compound in a one pot synthesis. The products are useful as dyes, and in particular as chromophores in electrochromic systems.Type: GrantFiled: March 29, 1999Date of Patent: June 5, 2001Assignee: Gentex CorporationInventors: Punam Giri, Harlan J. Byker, Kelvin L. Baumann
