Optically configurable charge-transfer materials and methods thereof

DWPI Title: Optical lens code comprises a film comprising a charge-transfer material and pattern disposed within the film in which the pattern comprises many first regions and many second regions
Abstract: The present invention relates to an optical code including a film of a charge-transfer material, as well as methods thereof. Described herein are optical codes having anisotropic and/or isotropic regions within the film, which can be provided in a pattern that serves as an optical code.
Use: Used as an optical lens code.
Advantage: The optical code can be optically written, rewritten, and read.
Novelty: Optical lens code comprises: a film (120) comprising a charge-transfer material (110), where the charge-transfer material comprises many domains, and each of the domains comprises a donor moiety (110A) and an acceptor moiety (110B); and a pattern disposed within the film, in which the pattern comprises many first regions and many second regions, where each of the first regions comprises a first optically anisotropic phase comprising many aligned domains arranged in an aligned columnar phase characterized by a first columnar director (111), and each of the second regions comprises an optically isotropic phase comprising many domains lacking alignment along the first columnar director or a second optically anisotropic phase comprising many aligned domains arranged in an aligned columnar phase characterized by a second columnar director that is different than first columnar director.
