Abstract

A new class of photo-initiated dopants, N-bromomides, function by the production of oxidizing agents rather than proton acids on exposure to ultraviolet light. Thus, a film of polyacetylene can be dipped into a methylene chloride solution of N-bromosuccinimide, dried, and irradiated to produce conductivities proportional to the initial concentration of the methylene chloride solution. Conductivities as high as 1 ohm/-1/ -cm/-1/ have been achieved by this technique. As with previous photo-initiated dopants, spatial resolution of doping can also be produced with N-bromosuccinimide using optical masks. In addition to operating by a different mechanism, these materials offer the important advantages of cheapness and commercial availability.
