Abstract :
Second harmonic generation has been observed from Langmuir-Blodgett multilayer arrays containing two active components. Both materials were based on long chain donor-acceptor dye compounds, but were designed with the donor-acceptor groups in opposite senses with respect to the hydrocarbon chain. Preliminary results indicate a significant enhancement of the second-order polarisability for this type of supermolecular array.
