 <\/p>\n

Amir recently attended the Konference on Optics, Atoms, and Laser Applications 2025 (KOALA)<\/span>.\u00a0 His poster entitled The push and the pull: Examining the effect of electron-donating and electron-withdrawing substituents in heteroleptic Cu(I) complexes was presented along with a flash talk.<\/p>\n

 <\/p>\n

The work described in the poster concnerns the photophysical properties of a series of heteroleptic Cu(I) complexes that incorporate the bulky ligand 4,4\u2032-dimesityl-2,2\u2032-bipyridine (diMESbipy), along with a family of 4,4′-bis(phenylethynyl)-2,2′-bipyridine derivatives bearing electronically modified phenyleneethynylene (PE) substituents. These derivatives include: 4,4′-bis(phenylethynyl)-2,2′-bipyridine (LH<\/sub>), 4,4′-bis((4-nitrophenyl)ethynyl)-2,2′-bipyridine (LNO\u2082<\/sub>), 4,4′-bis((4-methoxyphenyl)ethynyl)-2,2′-bipyridine (LOMe<\/sub>), and 4,4′-bis((perfluorophenyl)ethynyl)-2,2′-bipyridine (LPFP<\/sub>).\u00a0Cu(I) complexes show quasireversible Cu(I)\/Cu(II) redox with geometry change (tetrahedral \u2192 square planar). The MLCT transition was validated by TD\u2011DFT and Resonance Raman spectroscopy. Substituent electronics tune HOMO\/LUMO energies and CT behavior. Variable Temperature (VT) emission study reveal reduced emission, indicating absence of aggregation phenomenon.<\/p>\n
