Polyterthiophene-bearing pendant organomolybdenum complexes: electropolymerization of erythro-[Mo-2(mu-C5H5)(2)(CO)(4){mu-eta(2):eta(2)-C(R) C[C4HS(C4H3S-2)(2),5]}]

摘要

Terthiophenes bearing pendant organomolybdenum complexes, erythro-[Mo-2(eta-C5H5)(2)(CO)(4){mu-eta(2):eta(2)-C(R)= C[C4HS(C4H3S-2)(2)-2,5]} (R = H 1a or Ph 1b) were prepared by reaction of [Mo-2(eta-C5H5)(2)(CO)(4)] with 3'-alkynyl-2,2':5',2 "-tertiophenes. The molecular structures of 1a and 1b were identified by spectroscopic methods and X-ray diffraction. Cyclic voltammetry of 1a and 1b showed deposition of electroactive polymeric films on the electrode surface. The absorption spectra of 1a, 1b and their polymer films are presented. [References: 22]
