Abstract:
The development of novel luminescent iridium(III) complexes with highly tunable emission energy and versatile applications is of particular importance. In this Communication, a series of luminescent iridium(III) complexes supported by chromophoric pyridinium-derived N-heterocyclic carbene (NHC) ligands that display tunable emission from 516 to 682 nm were prepared. These complexes can be used as photocatalysts in photooxidation and photoreduction reactions and could have potential applications in pH sensing.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
