Investigation of the Triplet State Properties of Bis(chlorophyll)cyclophane and Its Partially Metalated Derivatives

Bis(chlorophyll)cyclophane was originally synthesized as a model system for the light to energy conversion in green plant photosynthesis. The molecule is two synthetically linked chlorophyll macrocycles stacked center to center with the Q(,y) transition dipoles of each macrocycle perpendicular. Zero, one, or two magnesium(II) ions can be inserted into the macrocycles. The properties of the photoexcited triplet state of the cyclophanes were studied using light modulated EPR (electron paramagnetic resonance) techniques on frozen solutions at 9K.
