摘要

A series of azobenzene-func-tionalized poly(alkyl aryl ether)den-drimers have been synthesized and their photochemical and photophysical properties in solution and as thin films have been investigated.Although the photochemical behavior of the azoden-drimers in solution indicated that the azobenzene units behave independently,very similar to the constituent monomer azobenzene unit,the properties of thin solid films of the dendrimers were distinctly different.The azoden-drimers,AzoGl,AzoG2,and AzoG3 were observed to form stable supercooled glasses,which showed long-wavelength absorption and red emission characteristics of J-aggregates of the azobenzene chromophores.Reversible photoinduced isomerization of the azodendrimers in the glassy state is described.
