M. Ravi et al., STRONG OPTICAL 2ND-HARMONIC GENERATION IN A CHIRAL DIAMINODICYANOQUINODIMETHANE SYSTEM, Journal of materials chemistry, 6(7), 1996, pp. 1119-1122
A series of amine donor-substituted dicyanoquinodimethane molecules wi
th large calculated hyperpolarizabilities has been investigated. Molec
ular and crystal structure details of a prototypical system are presen
ted. Moderate to strong phase-matched powder second-harmonic generatio
n is observed in chiral amine-substituted compounds.
