Abstract: A system and method for production and implementation of a photonic crystal forming, aqueous solution, may include: a block polymer mixture and at least one solvent, wherein the at least one solvent comprises water. The “color” of the photonic crystal solution may be set either through a single, or multiple, brush block copolymer mixtures (i.e., premixed coloring) or through layering of multiple layers of distinct single, or multiple, brush block copolymer mixtures. The system functions as an aqueous structural color (i.e., a photonic crystal) precursor, wherein applying the water-based color solution to a substrate, functions to provide a desired photonic crystal object arrangement possessing color reflective properties.

Abstract: Systems and methods used for or in connection to production and printing of a photonic crystal forming ink solution, which involve use of a block polymer mixture and optionally a solvent, wherein the color of the printed ink solution may be set either through a single or multiple block polymer mixtures (i.e. premixed coloring) or through printing multiple layers of distinct single or multiple block polymer mixtures (i.e. post print coloring). The composition(s) used by the systems and methods function as a structural color (i.e., a photonic crystal) precursor, wherein forming, loading, printing, and optional post-print processing of the ink solution on a substrate, function to provide a desired photonic crystal print object possessing reflective coloration properties.

Abstract: The invention provides novel compounds and methods that are useful in promoting reactions that proceed through an oxidative quenching pathway. In certain embodiments, the reactions comprise atom transfer radical polymerization.

Abstract: The present invention provides efficient processes for preparing brush polymers. In general, the process comprises three distinct reaction steps utilizing two separate catalysts. In the first step, the initiating compound comprising norbornene is contacted with a silane in the presence of a catalyst, thereby forming a silated intermediate. This silated intermediate is then contacted with a monomer in the presence of a catalyst via Group Transfer Polymerization (GTP). The resulting compound from GTP is contacted with a ring opening metathesis polymerization (ROMP) catalyst to prepare the brush polymer. Surprisingly, the brush polymers obtained from the above process are accessed in an efficient and rapid GTP methodology as compared to prior methods.
