Pentarylene- and Hexarylenebis(dicarboximide)s: Near-Infrared-Absorbing Polyaromatic Dyes

In the red: The synthesis and optical properties of homologous ladder‐type near‐infrared‐absorbing chromophores, namely, two pentarylenebis(dicarboximide)s (green traces; see picture) as well as a hexarylenebis(dicarboximide) (yellow trace) have been studied. A strong bathochromic shift of the absor...

Description
Summary:In the red: The synthesis and optical properties of homologous ladder‐type near‐infrared‐absorbing chromophores, namely, two pentarylenebis(dicarboximide)s (green traces; see picture) as well as a hexarylenebis(dicarboximide) (yellow trace) have been studied. A strong bathochromic shift of the absorption maximum is noted with an increasing degree of annulation as is evident from the other traces.
