Poly (1, 10-phenanthroline-3, 8-diyl) and its derivatives. Preparation, optical and electrochemical properties, solid structure, and their metal complexes
π-Conjugated poly (1, 10-phenanthroline-3, 8-diyl), PPhen, and its 5, 6-dialkoxy derivatives, PPhen (5, 6-OR) s, have been synthesized by using an organometallic polycondensation with a zerovalent nickel complex. They had average molecular weights of 4300-6800.
