A novel amphiphilic oligo(ethylene glycol)-C-60-hexadecaaniline (A(16)) tricomponent conjugate, C-60 >(A(16)-EG(43)), possessing a well-defined number of repeating aniline donor units and a hydrophilic ethylene glycol oligomer chain was synthesized. The compound is composed of a covalently bound donor-acceptor chromophore structure. Molecular self-assembly of C-60 >(A(16)-EG(43)) at the air-water interface formed a densely packed Langmuir monolayer with all highly hydrophobic fullerene cages located above the liquid interface. The monolayer can then be transferred onto a glass substrate via Langmuir-Blodgett (LB) deposition. LB multilayered thin films formed by multiple deposition of the monolayer yielded broadened optical absorption peaks extending beyond 600 nm into the 950 nm region, suggesting strong intermolecular interactions among the C-60 cages and the A(16) moieties. An X-ray reflectometry study clearly reveals that the Langmuir film at the air-water interface consists of a C-60 top layer and a bottom layer containing hexcadecaaniline and oligo( ethylene glycol) with gradually decreasing electron density over a distance of approximately 130 angstrom above bulk water. The pressure isotherm shows that the packing density of the C-60(A(16)-EG(43)) monolayer, corresponding to a molecular area of similar to 95 angstrom(2)/molecule, is similar to that of the surface area of the C60 monolayer. This result suggests that C-60 packing plays a dominant role in guiding the formation of the monolayer structure. Further photoexcitation of hexadecaaniline moieties of aligned (C60 >)-A(16) layers by a flash light source induces cross linking between adjacent A(16) segments forming an interlinked angstrom(16) array. Our results have demonstrated a unique fabrication method for preparing the aligned donor-acceptor array using strong intermolecular interactions between fullerenes as the molecular orientation guiding force in the Langmuir-Blodgett technique.
