    Abstract: The present disclosure provides for the development and applications of monomeric, oligomeric and/or polymeric semiconductor materials comprising a five-membered heteroaromatic unit (e.g., thiophene; furan; selenophene; etc.) that includes an acrylyl or an acrylyl-like (—C?C—CO—) side chain. The semiconductor materials can be used as organic semiconductors for use in electronic, optical, or optoelectronic devices such as organic thin film transistors and organic photovoltaics. The disclosed semiconductor materials (e.g., semiconducting polymer compounds) can be used as high performance semiconductors (e.g., for organic solar cells or organic photovoltaics (OPVs)), and the disclosed semiconductor materials can be used for other devices (e.g., organic thin film transistors (OTFTs) and sensors, etc.).

  • Patent number: 11930662
    Abstract: A light emitting device includes a transparent organic light emitting device and a quarter-wave plate. The transparent organic light emitting device includes a chiral complex emitter and produces circularly polarized light, and the quarter-wave plate converts the circularly polarized light into linearly polarized light. Generating linearly polarized light includes generating circularly polarized light via a transparent organic light emitting device including a chiral complex emitter, and passing the circularly polarized light through a quarter-wave plate to yield linearly polarized light.

  • Patent number: 11920070
    Abstract: The co-linear or near co-linear structure of bimetallic Janus-type two-coordinated metal complexes may allow for a large transition dipole moment that can enhance the radiative lifetime. The symmetric nature of the bimetallic Janus complexes diminishes or eliminates the polar nature of the monometallic carbene-metal-amide/arene complexes.
