Resumen:
The exploitationof excitedstatechemistryfor solarenergyconversionor photocatalysishas beencontinuouslyincreasing,and the needsof a transitionto a sustainablehumandevelop-mentindicatethis trendwill continue.In this scenario,the studyof mixedvalencesystemsin the excited stateoffersa uniqueopportunityto exploreexcitedstateelectrontransferreactivity,and, in a broadersense,excitedstatechemistry.This Conceptarticleanalyzesrecentcontributionsin the fieldof photo-inducedmixedvalencesystems,i.e.thosewherethe mixedvalencecoreis absentin the groundstatebut createduponlight absorption.The focusis on the utilizationof photoinducedintervalencechargetransferbands,detectedvia transientabsorptionspectroscopy,as key toolsto studyfundamentalphenomenalike donor/acceptorinversion,holedelocalization,coexistenceof excitedstatesand excitedstatenature,togetherwith applicationsin molecularelectronics.
