Abstract
Metal-free camphor-substituted pyrazinoporphyrazine was obtained by direct fusion of 1',7',7'-trimethylbicyclo[2.2.1]heptano-[2',3'-b]-2,3-dicyanopyrazine with NaOH. Metallo-complexes of 1',7',7'-trimethylbicyclo[2.2.1]heptano-[2',3'-b]-2,3-pyrazinoporphyrazine were synthesized by the template cyclotetramerization of dicarbonitrile with metal acetates. Spectral and mesomorphic properties of the synthesized complexes were studied.
Keywords: synthesis, properties, mesomorphism, metal complexes, camphor-substituted pyrazinopor-phyrazines
