TL;DR: In this article, the properties of various systems in a systematic way, within a wide range of wavelengths, and including the regions of onephoton, two-photon and threephoton absorption.
Spectral dependence of nonlinear optical properties of symmetrical octatetraynes with p-substituted phenyl end-groups.
TL;DR: This work investigates three newly synthesized aryl end-capped octatetraynes, exhibiting strong nonlinear absorption and nonlinear refraction properties, which can be attributed to the presence of aries end-groups with electron-withdrawing functional groups suitable for further extending the conjugation.
