Organic-anic hybrid films present special challenges and opportunities with respect
to potential applications, as well as for the observation of interesting physical phenomena.
Although the often disparate characteristics (., solubility and thermal stability) of the
ponents provide a potential barrier toward forming workable and convenient film
deposition strategies, recent results have demonstrated that not only is it possible to develop
suitable techniques for these materials but relatively simple processes are often sufficient
to yield high quality films. In the current review, some of these recent results anic-
anic hybrid films are discussed, with selected examples chosen from among the
deposition of sol-gel materials, self-assembled hybrids, Langmuir-Blodgett films, and
artificially layered materials. In addition to discussing film-deposition techniques, an effort
will also be made, where appropriate, to indicate how the resulting films might be useful
for applications such anic-anic electronic or photonic devices.
