Abstract

The third-order nonlinear optical properties and electric memory behavior of azobenzene polymers were influenced by different substituents. The nonlinear optical coefficients of polymer films measured using the Z-scan technique revealed that the polymers with different substituents exhibited different nonlinear absorption. The reversibility of sandwich memory devices based on the azobenzene polymers was dependant on the terminal substituent ...
