Summary: Three heteroleptic Ir(III) complexes with different electron-donating aryl groups were synthesized and their optical properties were investigated. It was found that all three complexes exhibited aggregation-induced phosphorescence emission (AIPE) behaviors, and the relationship between the size of organic ligands and AIPE behaviors was characterized. Ir-PhCz showed the best imaging of latent fingerprints due to its green light emission and high quantum yield.

Summary: In this work, an enantiomeric pair of chiral Pt(II) metallomesogens were synthesized and studied for their mesophase behaviors, chiroptical properties, and chirality transfer and amplification. The solutions of the Pt(II) complexes emitted green phosphorescence, but the amorphous form displayed orange-red phosphorescence. The emission color of the complex could be dramatically changed by grinding or heating, due to emerged intermolecular interactions. The chiroptical properties and LC self-assembly model of the complexes were proposed by theoretical calculations and measurements.

Summary: A novel water-soluble stilbene-type molecular photoswitch CP has been synthesized and its photoisomerization cycle and spectroscopic properties have been studied in acetonitrile and water. The efficient photoisomerization of CP in both solvents, along with the distinct fluorescence characteristics of the trans isomer, suggests that water-soluble coumarin-based photoswitches may be promising candidates for fluorescence imaging of biological samples.

Summary: This study utilizes optical modulation techniques to optimize the photophysical behavior of cyclometalated iridium(III) complexes by tailoring the auxiliary ligand for enhanced reactive oxygen species generation. One of the complexes, Ir-Q, exhibits superior singlet oxygen quantum efficiency of 0.92 due to the non-radiative intersystem crossover process initiated by its auxiliary ligand's optical properties. Furthermore, Ir-Q's robust multi-photon absorption spectra in the two-photon and three-photon domains offer potential applications in two-photon imaging-guided photodynamic therapy for deep-seated tumors.
