Abstract: Light-harvesting complex 2 (LH2) is an integral membrane protein in purple photosynthetic bacteria. This protein possesses two types of bacteriochlorophyll (BChl) a, termed B800 and B850, which exhibit lowest-energy absorption bands (Qy bands) around 800… read more here.

Abstract: We present the detailed characterization on the reconstitution of two cyclic tetrapyrrole pigments that have the same substituents but differ in the degree of hydrogenation in the macrocycles from bacteriochlorophyll (BChl) a (7,8,17,18‐tetrahydroporphyrin) into the… read more here.

Abstract: Natural bacteriochlorophyll (BChl) a from purple bacteria possesses the near-infrared absorption, high extinction coefficient and excellent photoelectric properties. It is a promising natural pigment sensitizer candidate for fabricating near-infrared responsive dye-sensitized solar cell (DSSC). However,… read more here.
