| Abstract | Coordination of dicobalt hexacarbonyl to the alkyne moiety of norbornene complexes contg. either ferrocene or η6-chlorobenzene-η5-cyclopentadienyliron hexafluorophosphate, gave two unique trimetallic complexes available for ROMP. Polymn. of each monomer using Grubbs second generation catalyst gave organoiron/organocobalt polynorbornenes with wt. av. mol. wt. of 55,300-69,000 with PDI of 1.2-1.9. Cyclic voltammetry data of monomers and polymers at -40° showed reversible redn. for cationic complexes contg. η6-benzene-η5-cyclopentadienyliron and for the dicobalt hexacarbonyl moieties while, a reversible oxidn. for the ferrocene contg. complex was obsd. Thermal anal. showed that the cobalt carbonyl moiety of the polymers undergoes degrdn. near 130°; however, the polymeric backbone was stable up to 350°. SEM and SEM-EDS indicated that the polynorbornenes possessed fine globular morphol. and that the distribution of iron and cobalt atoms was homogeneous on the macro-scale. [on SciFinder(R)] |
