Abstract
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 expected to find use as photo-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 ease of control of the orientation of naphthalocyanine rings and are expected of use as various functional materials.
Claims3
A vinyl-containing naphthalocyanine compound of the following formula (4):
- ##STR34## wherein each of Q.sup.1, Q.sup.2, Q.sup.3, and Q.sup.4 is a group of atoms to form a benzene ring or naphthalene ring fused to the adjacent pyrrole ring, at least one of the rings formed by Q.sup.1, Q.sup.2, Q.sup.3, and Q.sup.4 being a naphthalene ring,
- each of R.sup.1, R.sup.2, R.sup.3, and R.sup.4, which may be identical or different, is nitro, amino, alkyl or alkoxy group,
- s is 0 or an integer of 1 to 3 when Q.sup.1 forms a benzene ring, or 0 or an integer of 1 to 5 when Q.sup.1 forms a naphthalene ring,
- t is 0 or an integer of 1 to 4 when Q.sup.2 forms a benzene ring, or 0 or an integer of 1 to 6 when Q.sup.2 forms a naphthalene ring,
- u is 0 or an integer of 1 to 4 when Q.sup.3 forms a benzene ring, or 0 or an integer of 1 to 6 when Q.sup.3 forms a naphthalene ring,
- v is 0 or an integer of 1 to 4 when Q.sup.4 forms a benzene ring, or 0 or an integer of 1 to 6 when Q.sup.4 forms a naphthalene ring,
- with the proviso that s, t, u and v are not equal to 0 at the same time and the sum of s+t+u+v is an integer of at least 1,
- where s, t, u, and v are more than one, the corresponding R.sup.1, R.sup.2, R.sup.3, and R.sup.4 groups may be identical or different, and
- R.sup.5 is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
