Particular attention has been recently devoted to the development of biohybrid
photoconverters based on the bacterial Reaction Center (RC) of Rhodobacter sphaeroides.
This highly efficient photoenzyme has a conversion yield close to unit that makes it extremely
appealing in the field of artificial photosynthesis. Isolated RCs suffer of a limited absorption
cross-section in the visible spectral region that limits their applicative employment. Here we
report the synthesis of two heptamethine cyanine molecules, whose photophysical properties
make them potentially suitable as light harvesting antennas for the RC
