Abstract
Second-order molecular hyperpolarizabilities (gamma) of four tetraphenylchl
orin derivatives were measured by the Z-scan technique at 784 nm in the off
-resonant region and the enhancement in the hyperpolarizabilities of these
derivatives in comparison to the regular porphyrins with the same external
side-groups is explained on the basis of the difference in their Q-band osc
illator strengths. Copyright (C) 2001 John Wiley & Sons, Ltd.
