Min Chen, a biologist and associate professor of School of Biological Science of The University of Sydney. A/Prof Chen's research interests are primarily concerned with elucidating the molecular and biochemical mechanism of the energy-storing reactions in photosynthetic organisms, especially the function of novel photopigments in oxygenic photosynthetic bacteria.
Recently A/Prof Chen et al. discovered the fifth form chlorophyll, called Chlorophyll f
. This work is published in http://dx.doi.org/10.1126/science.1191127 Science in August 2010. The Chlorophyll f (absorption maximum at 706 nm in vitro), suggests that oxygenic photosynthesis can be extended even further into the infrared region, which may open up associated bioenergy applications. The function of Chlorophyll f in photosynthetic reactions is uncertain and the ecological distribution of chlorophyll f remains unknown.

Chlorophyll f
Chlorophyll f is a hypothesized form of chlorophyll that absorbs further in the red than other chlorophylls. It was reported from stromatolites from Western Australia's Shark Bay....
