Syntheses of a pyrene-based π-expanded ligand and the corresponding platinum(II) complex, bis[2-[(octylimino)methyl]-1-pyrenolato-N,O] platinum(II)

The molecular design and syntheses for a pyrene-based ligand, 1, were discussed. To demonstrate the potential of 1, the corresponding platinum(II) complex (2) was synthesized and characterized. Reflecting the expanded π-system of pyrene, bathochromic shift was observed in absorption spectra.
