Optimized trade-offs between triplet emission and transparency in Pt() acetylides through phenylsulfonyl units for achieving good optical power limiting performance

Optimized trade-offs between triplet emission and transparency in Pt() acetylides through phenylsulfonyl units for achieving good optical power limiting performance

Three Pt( ii ) acetylides have been prepared by coupling trans -[PtCl 2 (PBu 3 ) 2 ] to ethynyl aromatic ligands with electron-withdrawing phenylsulfonyl units in high yields (>85%). The investigation of their photophysical behavior has shown that the unique conjugation-breaking configuration of...

Zusammenfassung:Three Pt( ii ) acetylides have been prepared by coupling trans -[PtCl 2 (PBu 3 ) 2 ] to ethynyl aromatic ligands with electron-withdrawing phenylsulfonyl units in high yields (>85%). The investigation of their photophysical behavior has shown that the unique conjugation-breaking configuration of the -SO 2 - linker in the phenylsulfonyl units can afford a very short cut-off wavelength ( λ cut-off ) of
