Photosensitization is one of the most common and practical ways to generate excited states, particularly triplet states, especially when excitation at a desired wavelength cannot be achieved or when it does not lead to the desired excited state (Section 2.2). Good photosensitizers should absorb strongly in the region of interest and have sufficient excited-state lifetimes. For efficient energy transfer, the process should be exergonic. Table 6.22 lists some of the common photosensitizers and their typical applications.

Photosynthesis is the conversion of light energy into chemical potential in living organisms. It involves direct excitation, rapid and efficient energy and electron transfer processes and subsequent dark chemical reactions.
