A series of rhenium(I) and ruthenium(II) complexes of general formulas fac-[Re(CO)₃ClL] and [Ru(bpy)₂L](PF₆)₂ (L = N-(4-biphenyl)pyridine-2-carbaldimine (L1), N-[4-(4'-octadecyloxy)biphenyl]pyridine-2-carbaldimine (L2), (5-octadecyloxy)-2-pyridine-N-(4-biphenyl)carbaldimine (L3), and (5-octadecyloxy)-2-pyridine-N-[4-(4'-octadecyloxy)biphenyl]carbaldimine (L4)) were synthesized and characterized, andtheir photophysical properties were also studied. The X-ray crystal structures of fac-[Re(CO)₃ClL1] and[Ru(bpy)₂L1](PF₆)₂ have been determined. These complexes were capable of forming stable Langmuir-Blodgett (LB) films, as revealed by the study of their surface pressure-area (-A) isotherms, and theirsecond-harmonic generation (SHG) properties were also investigated.
