A novel alternating amphiphilic copolymer poly(tetra glycol-a-N,N-bis[2-(1H-1,2,3-triazol-1-yl)ethyl]-4-phenyl- diazenyl-aniline) [P(EG4-a-NAzo)] with azobenzene pendants was synthesized through the azide-alkyne click reaction, in which the hydrophilic unit was tetra glycol (EG4) and N,N-bis[2-(1H-1,2,3-triazol-1-yl)ethyl]-4-phenyldiazenyl-aniline (NAzo) performed the hydrophobic unit. P(EG4-a-NAzo) could self-assemble into worm-like aggregate in aqueous solution with initially low concentration. Because of its unique alternating topologies, the azobenzene moiety of P(EG4-a-NAzo) micelle could not pile up orderly. This novel azobenzene copolymer has arisen new thoughts and approaches for the molecular design of photo-functional polymers.
