LANGMUIR-BLODGETT-FILMS OF A THERMALLY LABILE-1 1 ADDUCT OF C-60 FULLERENE AND 8-(9-ANTHRYL)-7-OXAOCTANOIC ACID/

A novel amphiphilic C-60 derivative, C-60-AOOA, was prepared for Langm uir-Blodgett (LB) films by a thermally reversible Diels-Alder reaction of C-60 and an anthracene derivative with a carboxylic acid group sid e chain. This derivative showed a limiting surface area per molecule ( at zero pressure) as large as 0.92 nm(2), which is reasonable for a tr ue Langmuir monolayer of a C-60 derivative. LB films were formed on va rious substrates. Their structure and thermal behavior were studied by X-ray diffraction and FT-IR: the transferred C-60-AOOA decomposes upo n heat treatment, to form a C-60 layer and/or C-60/C-60-AOOA mixed lay ers.
