Phthalocyanine-based nonlinear optical (NLO) materials are reviewed, with particular emphasis on second-order effects. The requirements on materials and molecules for NLO activity are outlined before three recently studied families are briefly considered: asymmetrically substituted phthalocyanines (Pcs), subphthalocyanines.
