説明
<jats:title>Abstract</jats:title><jats:p>The reaction of bis(4,7‐tetrahydrothiopheniomethyl) benzofuran dibromide with aqueous tetramethylammonium hydroxide leads to a water‐soluble polyelectrolyte which can be film cast and thermolytically eliminated to give poly(4,7‐benzofuran vinylene) (PBFV). Subjection of bis(4,7‐tetrahydrothiopheniomethyl) benzothiophene dibromide to the same reaction sequence gives poly(4,7‐benzothiophene vinylene) (PBTV). UV‐VIS studies show that PBFV has a band gap of 2.76 eV, while PBTV has a band gap of 2.92 eV. These polymers are members of a new class of conjugated poly (arylene vinylene)s, in which heterocyclic pseudoaromatic rings are fused onto a poly(1,4‐phenylene vinylene) backbone. © 1994 John Wiley & Sons, Inc.</jats:p>
