Synthesis and Characterization of PBP Pincer Iridium Complexes and Their Application in Alkane Transfer Dehydrogenation [PDF]

open access: yes, 2016
This work reports on the synthesis of several new complexes of Ir supported by a diarylboryl/bis­(phosphine) PBP pincer ligand. The previously reported complexes (PBP)­Ir­(Ph)­(Cl) (1) and (PBP)­Ir­(H)­(Cl) (2) were converted to the new complexes (PBP ...

Spatially Separated Redox Centers in One‐Dimensional Sp2‐Carbon Covalent Organic Frameworks Enable Synergistic Photocatalytic Palladium Recovery and Bisphenol A Mineralization

open access: yesAdvanced Science
The simultaneous recovery of precious metal and pollutant degradation is often hindered by competing redox processes. Herein, we address this condition by designing a one‐dimensional covalent organic framework (COF), olefin‐linked iridium COF (Ole Ir ...
