Multicompartment micelles with tunable compartment solubility have been prepared in alcohols from a metallo-supramolecular poly(p-tetrafluoromethylstyrene)-block-poly(tert-butylacrylate)-block-poly(styrene)-[Ru]-poly(ethylene glycol) tetrablock quaterpolymer.
A series of substituted benzoyl radicals has been generated by laser flash photolysis of alpha-hydroxy ketones, alpha-amino ketones, and acyl and bis(acyl)phosphine oxides, all of which are used commercially as photoinitiators in free radical polymerizations. The benzoyl radicals have been studied by fast time-resolved infrared spectroscopy. The absolute rate constants for their reaction with n...
Water-soluble stimuli-responsive AB2 miktoarm star copolymers were prepared by atom transfer radical polymerisation of styrene followed by chain-end modification, polymerisation of either gamma-benzyl-L-glutamate N-carboxyanhydride or tert-butylacrylate and a final step of hydrolysis.
The chemical waste generated in today’s microelectronic fabrication processes has driven the need to develop a more environmentally benign process. Silicone fluids are linear methyl siloxanes that are non-toxic, not ozonedepleting and can be easily recycled. They are used as environmentally friendly alternatives in this study to develop conventional photoresists. After silylation, two conventio...
Pattern generation of well-controlled block copolymers (BCPs) with a high Flory-Huggins interaction parameter (χ) is important for applications in sub-20 nm nanolithography. We used mixed solvents of dimethylformamide (DMF) and toluene to control the morphology as well as the time to achieve the targeted morphology via self-assembly of BCPs. By precisely controlling the volume ratio of DMF and ...
