Holes, Electrons, Polarons, and Bipolarons and the Thermodynamics of Electrically Active Dopants in in these systems. Following this, experiments on both absorption isotherms and conductivity for vapor phase iodine in both polythiophene and azite are described and analyzed for the determination of relevant species. The formations of triiodide and pentaiodide ions are indicated, and bipolarons appear to form in polythiophene.

A PPP Variational-Perturbation Calculation of Hyperpolarizabilities of Conjugated Chainsoperties of polymers has become a point of interest: for example, the dramatic color change observed in polydiacetylene (PDA) solutions as a result of variations of concentration or temperature has been attributed to a planar-nonplanar conformational transition involving individual polymer chains..

Electric-Field Poling of Nonlinear Optical Polymershe polarization P of a dielectric which is quadratic in the applied electric field of the light beams E P = X(2):EE.The coupling coefficient x(2) is the second-order electric susceptibility tensor for the material. Maximizing the nonlinear susceptibility coefficients can result in large NLO effects.

Frequency and Temperature Variations of Cubic Susceptibility in Polydiacetylenesevices with high damage threshold. Since first pioneering works, both theoretical. and experimental. by Ecole Polytechnique’s group in France a great interest of these materials has been demonstrated. Before, organic materials have been known as having either a large second order hyperpolarizability

Studies of Monomer and Polymer Monolayers Using Optical Second and Third Harmonic Generation to study monolayers of various organic monomers -- vinyl stearate, octadecyl methacrylate and some diacetylene derivatives -- and their corresponding polymers spread at air/water interfaces. Different SHG signals are obtained from a pure water surface, and from water covered with monomer and polyme
