Conjugated Polymers: On the Parallel between the Electrical Conduction Mechanism and the Nonlinear Octivity upon doping and those responsible for the inherently large nonlinear optical response. We focus our attention on transpolyacetylene and its short oligomers, i.e., the polyene molecules. We present the results of recent theoretical calculations on the geometry relaxations taking place in the

Impact of Electron Quantum Confinement on Optical Nonlinearitiesrengths and level broadening. We separate the odd order susceptibilities in Franz-Keldysh and Stark contributions and show that the quantum confinement mostly affects the former. We also analyze the impact of quantum confinement on the figure of merit of the resonant optical Kerr effect and find tha

Structural and Electronic Properties of Push-Pull Conjugated Molecules: A Theoretical Investigation l data obtained by Graham et al. on the series of donor-acceptor molecules NO.-C.H.-(C≡C).-C.H.-NH. with n=0-3. Full geometry optimizations on all the molecules are compared to the X-ray diffraction data. Evolution of the electronic properties as a function of the number of triple bonds between

Polar and Non-Polar Organic Molecules, Crystals and Langmuir-Blodgett Films for Quadratic Nonlinear ”, “yellow” and “coloured” materials. For each class of transparency, examples of recent advances in the optimization of both molecular and macroscopic (crystalline, Langmuir-Blodgett) structures are discussed: polyphenyls for transparent materials, triamino-trinitro-benzene (TATB) for yellow compou

New Molecular Design for Noncentrosymmetric Crystal Structures: Lambda Shape Molecules for Frequencydesign for the noncentrosymmetric structures optimizing the phase matching properties. The lambda (Λ) shape molecules, which we have synthesized, stack easily along one direction and crystallize into the noncentrosymmetric space groups. We have found that in the most stable conformation obtained bot

Second Order Hyperpolarisabilities and Conformations of Functionalised Copolymersthe decrease in chromophore hyperpolarisability which may be attributed to dipolar interactions. These adverse effects are counteracted by the favorable orientation of the NLO-chromophores in the polymer.
