  • Photoactive compounds for vapor deposited organic photovoltaic devices
    Patent number: 12089426
    Abstract: Photoactive compounds are disclosed. The disclosed compounds can exhibit molecular structural elements tending to increase the evaporability of the compounds, such as by including geometric core disruption by use of conformationally restricted side groups instead of freely rotatable side groups or use of indandione moieties instead of dicyanomethyleneindanone moieties. The disclosed photoactive compounds include those with an imine-bridging linking moiety, which can shift the optical properties to a more red-shifted absorbance as compared to compounds with an alkene-bridging linking moiety. The disclosed photoactive compounds can be used in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.

  • Low fat peanut flour prepared by solvent extraction of oil from peanut flakes
    Patent number: 4190577
    Abstract: The present invention provides a method for the direct solvent extraction of oil from oil seeds to produce a low-fat proteinaceous material which comprises, wet heat conditioning oil bearing seeds to a moisture content of from 6 to 12%, flaking said wet heat conditioned oil seeds, dry heat conditioning said flaked oil seeds to a moisture content of from 1.9 to 6%, and treating said dry heat conditioned flakes with a solvent for the removal of the oil contained in said flakes.
