Abstract

Various π-conjugated polymers have been obtained by using organometallic polycondensations mediated by organotransition metal complexes. For example, Ni(0) complex-promoted dehalogenation polycondensation of dihaloaromatic compounds X-Ar-X affords poly(arylene)s, -(-Ar-)-_n. Pd-catalyzed polycondensation gives poly(arylene- ethynylene)s, -(-Ar-C≡C-Ar′-C≡C-)-_n. These polymers are electrochemically active, electrically conductive, and light-emitting. Their well-characterized linear structure brings about unique packing of the polymer molecules in the solid. In this review, we report their synthesis by organometallic polycondensations, their basic properties, the ordered structure in the solid, and applications for electronic and optical devices of π-conjugated polymers.

Key words

π-conjugated polymers - organometallic polycondensation - redox reaction - devices - catalysis

Kinetic parameters for the thermolytic reductive elimination reaction of NiEt₂(bpy) [1a] gives a calculated first-order-rate constant of an order of 10^-13 s^-1 at 300 K. On the other hand thermodynamic data of NiEt₂(bpy)(olefin) [1b] [c] (olefin = e.g., acrolein) and reductive elimination reaction of NiEt₂(bpy) in the presence of olefin [1a] give another calculated first-order-rate constant of an order of 10⁰ for reductive elimination of Et-Et from NiEt₂(bpy)(olefin):
