Electronic structure of covalently linked zinc bacteriochlorin molecular arrays: insights into molecular design for NIR light harvesting.

Pigment-based molecular arrays, especially those based on porphyrins, have been extensively studied as viable components of artificial light harvesting devices. Unlike porphyrins, bacteriochlorins absorb strongly in the NIR, yet little is known of the applicability of covalently linked bacteriochlorin-based arrays in this arena. To lay the foundation for… (More)
