5,6-Dibromo-1,10-phenanthroline and 2,9-di-n-butyl-5,6-dibromo-1,10-phenanthroline were polymerized using a Ni catalyst to afford helical polymers in which the phenanthroline moieties are densely stacked on top of each other.

Abstract Synthesis and characterization of 5,5′-bi(1,10-phenanthroline) (3) are described. Compound 3 was obtained by treatment of 5-chloro-1,10-phenanthroline (1) with 4-hydroxy- phthalonitrile (2) in the presence of K2CO3 as a base in DMF at room temperature for 25 h.

An electroluminescent element is disclosed, comprising an electroluminescent material and a fluorescent substance emitting light having an emission maximum at the wavelength different from that of light emitted from the electroluminescent material upon absorption of the light emitted from the electroluminescent material.
All possible symmetric bi-1,10-phenanthrolines (biphens) were synthesized by Ni-catalyzed coupling of corresponding halo-1,10-phenanthrolines. Their absorption and emission spectra were compared with those of phenanthroline as the reference compound. The spectral feature is explained by the molecular conformation, namely, coplanar 2,2'- and 3,3'-biphens and nearly bisected 4,4'- and 5,5'-biphens. The effects of additives, H+ or Zn2+, on the electronic spectra varied depending on the biphen ligand. The 2,2'-ligand formed a helical complex with Cu+ ions in a 2:2 ratio as revealed by spectroscopic titration and X-Ray analysis.
