Abstract: Methods, systems, and computer program products for storing data in, and reading data from, machine-readable optical labels are disclosed. A machine-readable optical label includes a data storage layer and a substrate having a reflective surface. The data storage layer defines a plurality of data storage patterns in each of a corresponding number of absorption bands. Each of the data storage patterns encodes a portion of the data stored in the label as a reflectivity of the label in the absorption band of the data storage pattern. The label is read by capturing images of the label in each of a plurality of color channels, with each color channel including one absorption band and excluding the other absorption bands. The data stored by each data storage pattern is then decoded from the image in the corresponding color channel.

Abstract: Embodiments of the present invention provides compounds, compositions, and methods for their preparation that provide efficient intramolecular fission, such that local order and strong nearest neighbor coupling is no longer a design constraint. Inventive materials include organic oligomers and polymers designed to exhibit strong intrachain donor-acceptor interactions and provide intramolecular singlet fission, whereby triplet populations can be generated in very high yields of, e.g., 170% or more.
