Novel naphthalocyanine compounds are provided, including nitro- and amino-substituted naphthalocyanine compounds and vinyl-containing naphthalocyanine compounds. The compounds have improved solubility and high purity and are used as light-functional materials such as dyes. Polymers are obtained using the vinyl-containing naphthalocyanine compounds. The polymers also have improved solubility, high purity, a high naphthalocyanine content and the orientation of the naphthalocyanine rings can easily be controlled, and are also used for various functional materials. |
