Phthalocyanines(PcS)and related compounds with their extended two-dimensional 18-π electronic delocalization are important targets to study nonlinear optical response.The tailorability of these macrocycles allows the finetuning of the chemical structure and nonlinear optical response.In this article,the design and main properties of phthalocyanines for second-and third-order nonlinear optical(NLO)and optical limiting applications are discussed,both at the microscopic and macroscopic level.
