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.

Abstract: Semi-permeable particle can be used to facilitate chemical reactions such as catalytic reactions. The semi-permeable particles are permeable to molecules having a molar mass of 1000 Daltons or less and have a mode particle size of at least 1 ?m. The semi-permeable particles have multiple discrete cavities containing an aqueous solution or suspension of an organic catalytic material. The semi-permeable particles are also impermeable to the organic catalytic materials so they are retained within the multiple discrete cavities, and the semi-permeable particles can be reused multiple times for the same or different chemical reaction.

Abstract: An imaging element is used to provide images based on the difference in index of refraction caused by imaging actinic radiation. Imaging provides desired results by the creation or elimination of light scattering in a two-phase imaging medium in which at least one phase contains a material that is capable of having a refractive index change in response to imaging actinic radiation. For example, if the refractive indices of the two phases are initially matched, imaging can cause a mismatch in imaged regions. Alternatively, the refractive indices of the two phases can be initially mismatched and imaging can create a match of refractive indices in imaged regions. An image can be produced using a controlled amount of imaging actinic radiation without any chemical processing or heating.
