A new polymeric cpd. contains units of formula (1): -(-porph(Me)-R1-C=C-C=CR2-)-n (1), where in (1) n = degree of polymerisation; R1,R2 = a direct bond, oxygen, imino, oxymethylene, or iminomethylene; porph(Me) = a polycyclic ring of porphyrin type with a central metal atom, with the metal atoms covalently bonded to the bridging group (2): -R1-C=C=C=C-R2- (2).Also claimed is the production of these polymers.The polycyclic ring is porphyrin, chlorin (sic), or corrin. The metal atom is silicon, germanium or aluminium. The ring system may be substd. with one or more gps. chosen from phenyl, biphenyl, terphenyl, naphthyl, anthryl, phenanthryl, perylenyl, or substd. by a divalent gp. |
