Jf. Piniella et al., SYNTHESIS, STRUCTURE AND 2ND-ORDER NONLINEAR-OPTICAL PROPERTIES OF HIGHLY FUNCTIONALIZED 6-AMINOPENTAFULVENES, Journal of materials chemistry, 8(3), 1998, pp. 619-627
Novel donor-acceptor functionalized pentafulvenes have been synthesize
d and characterized. Structural data have been obtained by single crys
tal X-ray diffraction. Their molecular and macroscopic second-order no
nlinear optical properties have been investigated, via electric field
induced second harmonic generation (EFISH) in solution and by second h
armonic generation with evanescent wave (SHEW) in the solid state.
