Organic materials for non-linear optics nitropyridine derivatives
Abstract
A variety of nitropyridine derivatives have been prepared and their second-harmonic generation (SHG) efficiencies measured in the powder form. Based on these powder measurements, two new compounds are the most non-linear substances known with absorption edge cutoffs less than 0.45 μm. © 1982.
