Abstract:
1. A dielectric thin film prepared on a substrate, the dielectric thin film comprising: a polymer material formed by homo-transport polymerization (“HTP”) of radical intermediates, the radical intermediates being formed from a first precursor, and the radical intermediates having a general structure (II): wherein: X Ar is an aromatic or a fluorinated-aromatic group moiety; n e comprises a free radical having an unpaired electron; and a second precursor incorporated into the polymer material, wherein the second precursor is removable from the dielectric film to create a porous dielectric film, wherein the second precursor comprises a general structure of (I):  wherein each Y is a leaving group selected from —COOR, NR
