| We recently developed method to site-isolate Grubbs' catalysts by encapsulating them in polydimethylsiloxane thimbles. Site-isolation keeps these catalysts from being poisoned by molecules on the outside of the thimbles and allows us to develop new cascade reactions. In this talk, I will discuss methods to site-isolate a variety of catalysts and reagents including the Grubbs' catalysts, MCPBA, LiAlH4, Grignard reagents, and water such that different combinations – including combinations that poison each other such as water and LiAlH4 – can be added to the same reaction vessel. In addition, I will discuss our synthesis of ultrahigh molecular weight comb block copolymers. These polymers can be synthesized in two steps and assembled in the solid state into ordered morphologies with domain sizes exceeding 200 nm. These polymers are new photonic band gap materials that may have applications in size regimes beyond visible light.
