Thin Film Single Crystal Growth of a Nonlinear Optical Polymer
Abstract
Over the past decade macromolecules with an extended chain geometry and conjugated backbone electronic structure have been established as novel electronic and optical materials. This includes photo-, thermo-, solvato-, and electro-chromism, large electrical and photo-conductivities and unique linear and nonlinear optical properties among others. Polydiacetylenes, a class of a conjugated polymers are considered possible candidate material for all optical switching and logic applications. In the transparent regime they possess some of the largest third order nonlinear optical susceptibilities. In general, it is extremely difficult to grow bulk polymeric single crystals. Polydiacetylenes, however, can be grown to large size in single crystal form. Single crystals of polydiacetylene can be directly grown from monomer single crystals through solid-state polymerization by heat. (js)
