Share and share alike : Chlorophylls are appended to rigid linkers with threefold symmetry. The efficiency of both energy and charge transfer between the chlorophylls is controlled by the structure of the central linker. Direct chlorophyll–ethynyl linkage facilitates charge sharing between all three chlorophylls on the EPR/ENDOR timescale (10 7 Hz). ENDOR=electron nuclear double resonance.
