Abstract

The synthesis and response upon light irradiation of azoresveratrol and six derivatives are reported. While UV irradiation of para-hydroxy trans compounds leads to thermally unstable cis isomers, the para-methoxy and the para-phosphoric ester substituents result in reaching a high conversion and increasing the thermal stability. In addition, the phosphoric ester azo derivative presents similar properties in organic and aqueous solutions, opening the way towards biological applications.
