PREPARATION OF 3-LONG-CHAIN SUBSTITUTED 5-MEMBERED HETEROARYLENES AND STUDIES OF THEIR LANGMUIR-BLODGETT FILM FORMATION

Abstract The synthesis of amphiphilic thiophene 1 and pyrrole 5 were achieved via Wittig and Friedel-Crafts reactions respectively. The ability of 1 and 5, as well as 3-heptadecylthiophene and poly(3-heptadecylthiophene), to form Langmuir-Blodgett films are discussed.
