Chromicity in Poly(aryleneethynylene)s

摘要

The chromicity of poly(aryleneethynylene)s (PAE) is discussed and described in this contribution. Four different types of PAEs will be scrutinized a) dialkyl-poly(para-phenylene-ethynylene)s (dialkyl-PPEs), b) dialkoxy-PPEs, c) acceptor substituted PPEs, and d) heteroaryleneethynylenes that contain benzothiadiazole units in their main chain. We will shortly describe their syntheses and then discuss their spectral properties in absorption and emission in solution and in thin films.
