Abstract
We synthesized the arylazo compounds 3a-c, 5a,b, 5d, 5f, 6b, 6d, 6f, 7 -9 containing ferrocene as electron donor group and different electron accepters or donors in order to tune the absorption wavelength. Compo unds 5f, 6f, 8, 9 were incorporated as side chains in liquid crystalli ne polymers. As holographic experiments showed these materials are not superior to polymers containing arylazochromophores without the ferro cene moiety like compounds 10, 11. In addition, the solvatochromism of the ferrocene azo compounds has been measured as a first test of thei r first order NLO activity. Only compound 9 showed remarkable values.
