Abstract
The present invention provides monomers, analogs, and/or derivatives of bisphenols substituted with one or more fluoromethyl groups. These monomers, analogs, and/or derivatives can be used to form oligomers and/or polymers, which in turn can be used to make compounds with dielectric properties suitable for dielectric materials, including for example, use in energy dense capacitors. In a preferred embodiment, the compounds can comprise a polycarbonate of a homopolymer, copolymer, and/or terpolymer of a bisphenol with one or more fluoromethyl substitution groups. In an aspect of the invention the compounds chosen can be selected based on various desired characteristics, including, for example, their energy density, glass transition temperature, dielectric loss, and/or dipole density.
