Abstract

We report on linear and third order nonlinear optical properties of the quinoid molecule 5, 5′-bis (3, 5-di-tert-butyl-4-oxo-2, 5-cyclohexadiene-1-ylidene)-5, 5′-dihydro-2, 2′- bithiophene. Variable angle spectroscopic ellipsometry has been used to determine the dispersion of the dielectric in a spectral range from the near infrared to the near ultraviolet. We have measured a high value of the index of refraction in the transparency region (ie, n ...
