title: Sexterrylenetetracarboxylic Bisimides: NIR Dyes.
abstract: Sexterrylenehexacarboxylic bisimides, extended peri-arylenes with the alignment of six peri-arranged naphthalene units, were prepared by Suzuki cross coupling and subsequent oxidative ring closure reactions of the perylene units and exhibit NIR absorption at 945 nm. Intermediates are strongly fluorescent with an increased Stokes shift because of dynamic processes.
