摘要:
Optical spectra of the complexes, trans-ClCoN4C=CC6H5, trans-CoN4(C=CC6H5)2 and [-CoN4C=C-p-C6H4C=C-]n, (where N4=3,9-dimethyl-4,8-diazaundecane-2,10-dione dioxime) show absorptions associated with pi-pi* transitions of the acetylenic unit and indicate an extended pi-electron conjugation through the metal sites on the chain in the polymeric complex.
