DESCRIPTION:Inspired by natural photosynthesis\, there is a vision that fu
 els and chemicals can be synthesized using Earth's basic elements (i.e.\, 
 H2O\, CO2\, N2) and removable energy. This concept has given rise to the m
 ultidisciplinary field of artificial photosynthesis.2-4 One of the most ap
 pealing research areas in this context is the mechanistic understanding of
  multi-electron\, multi-proton processes central to transforming small mol
 ecules in artificial photosynthesis. These studies have provided new insig
 hts into the processes and led to the discovery of new reactivity.\nIn thi
 s regard\, we will discuss a procedure for synthesizing water oxidation ca
 talysts and an ideal reaction to extract reductive equivalents. On the red
 uctive side\, we have discovered well-defined coordination complexes that 
 are highly efficient homogeneous catalysts for reducing water\,1\, and CO2
 2 and organic substrates such as ketones\, aldehydes\, and olefins.3 The l
 ow valent metal intermediates also promote the challenging visible-light r
 eductive radical C-C bond formations from unactivated chloroalkanes\, whic
 h opens new avenues in photoredox catalysis.4 We will also discuss how to 
 control the selectivity between water reduction and the reduction of organ
 ic functionalities. Finally\, mechanistic understanding unlocks the reacti
 vity of the Ir-based photosensitizers
