摘要

We present a series of small-molecular trisazobenzene chromophores, including, for instance, 1, 3, 5-tris {[4-[4-[(4-cyanophenyl) azo] phenoxy] butyryl] amino} benzene that feature a remarkably stable light-induced orientation in initially amorphous thin-film architectures. It is demonstrated that for optimal performance it is critical to design chemical structures that allow formation of both an amorphous and a liquid-crystalline phase. In the ...
