COMPUTATIONAL STUDY ON SECOND-ORDER NONLINEAR OPTICAL PROPERTIES OF DONOR-ACCEPTOR SUBSTITUTED COPPER PHTHALOCYANINES
Abstract
The second-order nonlinear optical properties (NLO) of a set of copper phthalocyanines have
been studied based on density functional theory calculations. Our calculations show that
they possess high value NLO properties. The first hyperpolarizabilities can be enhanced by
position and number of donor-acceptor substituents along the phthalocyanine core.
