Design and synthesis of new electron-acceptor chromophores for incorporation into dendrons and dendrimers for enhanced reverse saturable absorption

摘要

During the past few years our research groups have collaborated in the design of new organic materials that form highly absorbing transient charge states upon intense laser irradiation.Chromophores such as bis-(diphenylamino)diphenylpolyenes or dithienyl-polyenes form highly stable bipolaronic dications when oxidized in solution with antimony pentachloride.
