  • Patent number: 10002214
    Abstract: Compound libraries, systems, methods, and apparatus, including computer program apparatus, are described for implementing techniques for processing data from a combinatorial inquiry to determine materials of use in various photoelectronic devices, e.g., organic light emitting diodes. The libraries include a collection of putative compounds of use as components of OLED devices, which are cross-referenced with one or more electronic property relevant to the efficacy of the compounds in an OLED device. The techniques broadly include receiving data from a chemical experiment on a library of materials having a plurality of members and generating a queriable representation of the chemical experiment. The chemical experiment is optionally an in silico experiment.
