Synthesis of Alkoxy Substituted Metallicphthalocyanine and Study of Their Spectral Characteristics

Two kinds of metallicphthalocyanine compounds with different alkoxy-substituted structures were synthesized in this paper.The molecular structures of the compounds were identified by element analysis and infrared spectra.The UV-VIS spectra of the two alkoxy substituted compounds in the MMA were measured.The result indicated that two synthesized com-pounds have obvious absorption at near infrared wave band,optical density was near 3,and visible light transmittance of them are all higher than 57%.They can be used as near infrared absorbers for laser protection.
