M. Bourgault et al., SYNTHESIS AND 2ND-ORDER NONLINEAR-OPTICAL PROPERTIES OF NEW BIPYRIDYLMETAL-COMPLEXES, Journal of the Chemical Society, Chemical Communications, (21), 1993, pp. 1623-1624
The synthesis and characterisation of a series of new pi-donor substit
uted vinyl bipyridines and their rhenium, zinc and mercury complexes {
donor = 4-R2N-C6H4- [R2N = Me2N, Bun2N, (Me)(OCt(n)N)]; (eta5-C5H5)Fe(
eta5-C5H4-)} with large nonlinear optical properties are presented; EF
ISH experiments at 1.34 mum show that complexation leads to a strong e
nhancement (by a factor of 3 to 9) of the molecular hyperpolarisabilit
y beta(0).
