Publication number: 20230045339Abstract: A method to control the density of a three-dimensional photonic crystal template involves changing the irradiation time from at least four laser beams to yield a periodic percolating matrix of mass and voids free of condensed matter from a photoresist composition. The photoresist composition includes a photoinitiator at a concentration where the dose or irradiation is controlled by the irradiation time and is less than the irradiation time that would convert all photoinitiator to initiating species such that the density of the three-dimensional photonic crystal template differs for different irradiation times. A deposition of reflecting or absorbing particles can be patterned on the surface of the photoresist composition to form a template with varying densities above different areas of the substrate.Type: ApplicationFiled: August 5, 2021Publication date: February 9, 2023Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., The Board of Trustees of the University of IllinoisInventors: Shailesh N.

Publication number: 20230042586Abstract: A three-dimensional photonic crystal template on a reflective substrate displays a periodic patterned from multibeam interference lithography with constructive volumes of a cured photoresist composition and destructive volumes that are voids free of mass containing defects and where the reflective substrate is conductive. A method to generate the three-dimensional photonic crystal template includes using at least four laser beams of unequal intensity, oriented such that a dose of light controlled by the irradiation time generates the periodic pattern with a small dose, where the light reflected from the substrate is insufficient to activate a threshold quantity of photoinitiator in the destructive volumes for the formation of any anomalous condensed matter in the intended void volume.Type: ApplicationFiled: August 5, 2021Publication date: February 9, 2023Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., The Board of Trustees of the University of IllinoisInventors: Shailesh N.

Publication number: 20230044483Abstract: A method of decomposing a cured aromatic epoxy resin uses a molten salt bath at less than about 350° C. The molten salt bath includes a plurality of alkali metal hydroxides. The cured aromatic epoxy resin can be in intimate physical contact with a metal or alloy. The cured aromatic epoxy resin can be patterned by a lithographic method. The lithographic method can be multibeam interference lithography to form a three-dimensional photonic crystal template on a conductive substrate for electrodeposition of metal. Contacting the three-dimensional photonic crystal template with the electrodeposited metal with the molten salt bath can form a metal matrix device displaying a periodic pattern that is the inverse of the periodic pattern of the decomposed three-dimensional photonic crystal template.Type: ApplicationFiled: August 5, 2021Publication date: February 9, 2023Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., The Board of Trustees of the University of IllinoisInventors: Shailesh N.

Publication number: 20230044343Abstract: A method to form a three-dimensional photonic crystal template with a gradient structure involves irradiating a photoresist composition of a thickness of at least 15 ?m from at least four laser beams to yield a periodic patterned with a percolating matrix of mass in constructive volumes of a cured photoresist composition and destructive volumes of voids free of condensed matter where the proportion of constructive volume displays a gradient from the irradiated surface to the substrate after development. For a given light intensity, photoinitiator concentration in the photoresist composition, and a given thickness, by irradiating for a relatively short period, a three-dimensional photonic crystal template displaying a gradient having greater constructive volume proximal the air interface forms and a relatively long irradiation period results in a gradient having greater constructive volume proximal the substrate.Type: ApplicationFiled: August 5, 2021Publication date: February 9, 2023Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., The Board of Trustees of the University of IllinoisInventors: Shailesh N.

Publication number: 20230040709Abstract: Photoredox catalysis has emerged as a powerful strategy for C—O cross-coupling reactions. We herein report a new class of tridentate pyridinophane ligands RN3 that allow for detailed mechanistic studies of the photocatalytic C—O coupling reaction. The derived (RN3)Ni complexes are active C—O cross-coupling photocatalysts under mild conditions and without an additional photocatalyst. We also utilized the RN3 ligands to study the essential but so far putative steps involving paramagnetic Ni species in a proposed catalytic cycle: the oxidative addition of an aryl bromide to a Ni(I) species, the ligand exchange at a Ni(III) center, and the C—O reductive elimination from a Ni(III) species.Type: ApplicationFiled: June 6, 2022Publication date: February 9, 2023Applicant: The Board of Trustees of the University of IllinoisInventors: Liviu M.
