Rigid-rod push–pull naphthalenediimide photosystems

Rigid-rod push-pull naphthalenediimide photosystems.

Design, synthesis and evaluation of advanced rigid-rod pi-stack photosystems with asymmetric scaffolds are reported. The influence of push-pull rods on self-organization, photoinduced charge separation and photosynthetic activity is investigated and turns out to be surprisingly small overall.

A rigid sublimable naphthalenediimide cyclophane as model compound for UHV STM experiments.

The design, synthesis and characterization of a rigid naphthalenediimide cyclophane as a model compound for ultrahigh vacuum (UHV) STM experiments are described together with first self-assembly investigations on an Au(111) substrate displaying the formation of densely packed parallel rows of molecules.
