摘要：
The linear optical properties of Langmuir-Blodgett films of alternating layers of the electron acceptor, octadecylthiobenzoquinone, and the electron donor 7-(N- octadodecylaminomethyl)-8-16-dioxadibenzo[f,g]perylene indicate that only a weak intermolecular contact is formed at the interface between donors and acceptors. Structural data based on linear dichroism and X-ray diffraction show that the intermolecular contact between donor and acceptor layers is possible due to the carbonyl lonepairs in the acceptor, which are directed towards the interface. The prospects for donor-acceptor interfaces in nonlinear optical materials are discussed.
