Studies on The Synthesis of Conjucted Five-Six Biheterocyclic Cyanine Dye Series R. M. Abu El-Hamd, A. I. M. Koraiem From Department of Chemistry, Faculty of Science, Aswan, Egypt. Synthesis of new types of pyrazolo (4,3-d)-benzoxazine/quinoxaline cyanine dyes covering dimethine, mono (di)-cationic styryl, azastyryl and merocyanines were achieved by interaction of 3-methyl-l-phenyl pyrazolo (4,3-d)-benzoxazine/quinoxaline with active carbonyl components. The newly synthesized dyes were identified by spectral data. Keywords: Heterocyclic dye series, pyrazolo (4, 3-d)-benzoxazine/quinoxaline cyanine dyes, spectral data R. M. Abu El-Hamd, A. I. M.
