摘要: Bacteriochlorophylls—natural pigments for absorption of near-infrared (NIR) light—underlie light-absorption and energy transduction in photosynthetic bacteria. Capturing utilizing NIR light is valuable fields ranging from artificial photosynthesis to photomedicine (photodynamic therapy, imaging, diagnostics). The desired photochemical features may be best elicited with multicomponent architectures that support efficient excited-state and/or electron transfer, yet few such arrays containing bacteriochlorins (the core chromophore bacteriochlorophylls) are known. This review outlines three synthetic approaches toward bacteriochlorins, surveys all known bacteriochlorin arrays, compares molecular design strategies light-harvesting bacteriochlorinsversus better known) porphyrins.
