ABSTRACT
Interest in conjugated polymers as a new class of advanced electronic materials began in the late 1970s with the discovery of metallic, electrical conductivity in oxidatively doped polyacetylene (CH)* [1,2]. Since then, tremendous effort has been devoted to the design, synthesis, and study of conjugated polymers. Substan tial π-electron delocalization along the conjugated polymer backbone gives rise to unique optical, electronic, and nonlinear optical properties in these materials [3-10]. These properties have led to a wide variety of proposed technological applications such as electrical conductors, nonlinear optical devices, polymer light-emitting diodes (LEDs), sensors, electrochromic devices, batteries, anti static coatings, and transistors [7-14].
