Mesogenic Materials With Anomalous Birefringence Dispersion And High Second Order Susceptibility (X(2))

View page
US Patent:
6569504, May 27, 2003
Filed:
Aug 11, 2000
Appl. No.:
09/639500
Inventors:
David M. Walba - Boulder CO
Daniel J. Dyer - Pasadena CA
Uwe Muller - Berlin, DE
Peter Cobben - Waalre, NL
Xin Hua Chen - Boulder CO
William Thurmes - Longmont CO
Michael Wand - Boulder CO
Assignee:
Displaytech, Inc. - Longmont CO
International Classification:
C09K 1952
US Classification:
428 11, 25229901, 2522992, 2522996, 25229963, 25229961
Abstract:
This invention provides LC compositions useful as birefringent materials in electrooptic devices which exhibit zero or low negatively sloped birefringence dispersioon (e. g. , exhibiting positive birefringence dispersion significantly lower than that of currently available LC compositions) or more preferably positively sloped birefringence dispersion in which birefringence of the material increases with wavelength. The invention provides compounds useful as components of LC compositions which exhibit negative birefringence where n is higher than n. The compounds of this invention are dimers of LC-like compounds in which the monomers are linked to each other through a high birefringence moiety (dimerization linker). The LC monomers consist of an LC core and one or two tail groups. Preferred monomers for this invention have low birefringence in comparison to the birefringence of the monomer linking moiety.

US Patent:
7374948, May 20, 2008
Filed:
May 31, 2005
Appl. No.:
11/141433
Inventors:
David M Walba - Boulder CO, US
Noel A. Clark - Boulder CO, US
Assignee:
The Regents of the University of Colorado - Boulder CO
International Classification:
G01N 21/62
C09K 19/52
C09K 19/54
US Classification:
436164, 436149, 436805, 436806, 25229901, 2522995
Abstract:
The disclosure provides methods for the determination of the enantiomeric excess of chiral compounds. The methods involve doping a chiral analyte into an achiral liquid crystal host to form a chiral dopant/host liquid crystal mixture. An electro-optic signature of the mixture is then determined and is used to calculate the enantiomeric excess of the chiral analyte. The disclosure also provides systems for performing the disclosed methods of determining enantiomeric excess.
