“…Methyl ester of metal-free bacteriopheophorbide-f possessing ethyl (E) and methyl (M) groups at the 8-and 12-positions, respectively, (=[EM]BPhe-f M , see Scheme 2) has already been reported to be synthesized from Chls-a (Tamiaki et al 1999) and b (Risch et al 1988;Simpson and Smith 1988;Tamiaki et al 2000). The other homologs, [EE]-, [PE]-, and [IE]BPhes-f M (P = propyl and I = isobutyl), were also obtained from the corresponding BChld homologs (Tamiaki et al 2003).…”

Bacteriochlorophyll(BChl)-f which has not yet been found in natural phototrophs was prepared by chemically modifying chlorophyll-b. The retention time of reverse-phase high-performance liquid chromatography of the synthetic monomeric BChl-f as well as its visible absorption and fluorescence emission spectra in a solution were identified and compared with other naturally occurring chlorophyll pigments obtained from the main light-harvesting antenna systems of green sulfur bacteria, BChls-c/d/e. Based on the above data, BChl-f was below the level of detection in three strains of green photosynthetic bacteria producing BChl-e.
