| abstract |
A bis(aryl)acetal has structure (1) n nwherein Ar 1 and Ar 2 are each independently an aryl or heteroaryl group. R 1 and R 2 are each independently hydrogen, or an alkyl, cycloalkyl, aryl, or heteroaryl group, and R 1 and R 2 can connect directly with each other. Y is a leaving group or a boron-containing functional group bonded to Ar 2 via a boron atom. The bis(aryl)acetal is useful as a monomer that can be polymerized to yield a polymer with an acid-sensitive backbone. |
