Transition-Metal Complexes for Triplet–Triplet Annihilation-Based Energy Upconversion

  • Chapter
Organometallics and Related Molecules for Energy Conversion

Part of the book series: Green Chemistry and Sustainable Technology ((GCST))

Abstract

In recent years, significant progress has been achieved in the field of triplet–triplet annihilation (TTA)-based energy upconversion, in which transition-metal complexes as the sensitizers play a key role. These complexes are different from organic fluorophores because the triplet excited states, instead of the singlet excited states, are populated with a high intersystem crossing (ISC) efficiency upon photoexcitation. Meanwhile, the long-lived triplet excited states in the microsecond range are observed for these complexes. All these properties are favorable when transition-metal complexes, including Ir(III), Pd(II), Pt(II), Ru(II), Zn(II), Re(I), Cu(I), and Au(III) complexes summarized herein, are used as sensitizers for TTA upconversion. Moreover, some examples of organic sensitizers and the applications of TTA upconversion systems are also summarized.
