Their electrochemical and photophysical properties have also been studied. Two amphiphilic platinum(II)2, 6‐bis(1‐dodecyl‐1, 2, 3‐triazol‐4‐yl)pyridine complexes (<bold>3‐Cl</bold> and <bold>8</bold>) were found to form stable and reproducible Langmuir–Blodgett (LB) films at the air/water interface. These LB films were characterized by the study of their surface‐pressure–molecular‐area (π–A) isotherms, XRD, and IR and polarized‐IR spectroscopy.</p> </abstract>
