By virtue of the electron-donating and electron-withdrawing properties of t
he thiazole ring, a new soluble rigid-rod organometallic polymer containing
elecrtron-donating and electron-withdrawing trans-[-Pt-(PBu3)(2)-C=C-R-C=C
-](n) (R = bithiazolediyl) groups is prepared by CuI-catalyzed dehydrohalog
enation. The thermal properties and the optical absorption and photolumines
cence spectra of the polymer are reported. The polymer with a singlet emiss
ion peak at 539 nm and photoconducting in a single-layer sandwich structure
photocell. The optical gap of the polymer is reduced compared to that for
the oligothienyl analogue.
