Abstract

A series of substituted fluorenes with vinyl groups as reactive sites were synthesized and characterized. Fluorene‐based polymers with vinyl groups as end chains and side chains functionalities were also prepared. In both cases, successful preparation of functionalized Parylene C films (modylayers) was achieved. The set of spectral methods used has allowed us to conclude that such functionalization is based on the chemical reaction of double bonds with xylylene radicals during deposition process. Parylene C films chemically modified with specially synthesized polyfluorenes showed PL quantum efficiency comparable with neat polyfluorenes.

Critical current measurements were made using films of YBa2Cu307. d prepared by a metalorganic process. The film thickness was purposely reduced to about 15 nm so that measurements of the critical current could be made at temperatures of 4.2 K with reasonable width. Magnetic fields to 5.53 T were ap
