T. Bjornholm et al., DONOR-ACCEPTOR INTERFACES IN LANGMUIR-BLODGETT-FILMS - STRUCTURAL ANDOPTICAL-FEATURES RELATED TO NONLINEAR-OPTICAL PROPERTIES, Synthetic metals, 57(1), 1993, pp. 3813-3818
The linear optical properties of Langmuir-Blodgett films of alternatin
g layers of the electron acceptor, octadecylthiobenzoquinone, and the
electron donor 7-(N- dodecylaminomethyl)-8-16-dioxadibenzo[f,g]perylen
e indicate that only a weak intermolecular contact is formed at the in
terface between donors and acceptors. Structural data based on linear
dichroism and X-ray diffraction show that the intermolecular contact b
etween donor and acceptor layers is possible due to the carbonyl lonep
airs in the acceptor, which are directed towards the interface. The pr
ospects for donor-acceptor interfaces in nonlinear optical materials a
re discussed.
