Enhanced Third Order Nonlinearity in Macrocyclic Compounds
TL;DR: In this article, the third-order nonlinear optical susceptibilities of macrocyclic compounds such as phthalocyanines and porphyrins are determined for the vacuum deposited and spin coated thin films by optical third-harmonic generation measurements at a wavelength of 1907 nm.
Journal ArticleDOI
Enhancement of Optical Third Order Nonlinearity in Main-Chain Oriented Polythiophenes
TL;DR: The third order nonlinear responses for poly(3-alkylthiophene) polymers were investigated in this article, where uniaxial stretching of the polymer film was carried out to align the polymer backbone.
Journal ArticleDOI
AB Initio Calculation of the Polarizability and Hyperpolarizabilrties of Infinite Periodic Polymers by the Sum-Overstates approach
TL;DR: In this article, the applicability of the Genkin-Mednis perturbative approach to the ab initio calculation of the static (hyper)polarizabilities of infinite periodic polymers is investigated.
Journal ArticleDOI
Pyridine N-Oxides As Polymeric Nonlinear Optical Materials
TL;DR: In this article, three polymers containing pyridine N-oxide imine pendant moieties were prepared and examined, and side reactions involving the Noxide group during polymerization were postulated as leading to the lack of mesomorphism in these materials although the π-chromophore remains essentially intact for the bulk of the material as judged by UV-Vis and other spectral data.

Nonlinear optical properties of iodoform complexes
TL;DR: In this paper, measurements of the electrooptic effect and second harmonic generation on three complexes of iodoform with sulphur, quinoline and tetramine are presented.
