1 Introduction Tripodal ligands, consisting of a central metal-coordinating atom flanked by three chelating phosphine arms, are well-known for their ability to create a rigid coordination environment around a metal center. Therefore, they have found extensive applications in homogeneous catalysis, including fundamental processes such as CO2 reduction [1] and N2 fixation [2].

Bicyclic Sulfonium Pincer Ligand with a Thiatriptycenium Backbone - Synthesis and Applications in π-Acid Catalysis A novel PSP-pincer ligand featuring a sulfonium cation at the bridgehead position of its rigid triptycene-like scaffold was synthesized and metallated with a bis-cationic Pt(II) center. The resulting tris-cationic Pt(II) complex exhibits excellent photostability and improved catalytic performance compared to its analogue with the previously reported sulfonium pincer ligand.
