Synthesis of a Novel Cyclic Chlorophyll Hetero-Dyad as a Model Compound for Stacked Chlorophylls Found in Photosynthetic Systems

A covalently doubly linked cyclic chlorophyll hetero‐dyad was stereospecifically prepared as a model for naturally stacked chlorophyll suprastructures. In the synthetic dyad, two composite macrocycles are situated very close to each other such that the Qy transition dipole moments intramolecularly i...

Zusammenfassung:A covalently doubly linked cyclic chlorophyll hetero‐dyad was stereospecifically prepared as a model for naturally stacked chlorophyll suprastructures. In the synthetic dyad, two composite macrocycles are situated very close to each other such that the Qy transition dipole moments intramolecularly interact to give intense circular dichroism peaks.
