dc.description.abstract | A rare family of six discrete binuclear [PdCl(PEt3)2] phenylene ethynylene rods with alkoxy side chains
(methoxy, ethoxy and heptoxy) have been developed, and their solid-state photoluminescence results
have been presented and discussed. The shorter bridging ligands are of the general formula H–CuC–
C6H2(R)2–CuC–H, where R = H, OCH3, OC2H5, and OC7H15, whereas the longer ones are based on H–
CuC–C6H4–CuC–C6H2(R)2–CuC–C6H4–CuC–H, where R = OCH3, OC2H5. These ligands display
increasing length in both the main dimension (backbone length) as well as the number of carbons in the
side chains (R, alkoxide side chain) that stem from the central phenylene moiety. The X-ray crystal structures
of two of the prepared complexes are reported: one corresponds to a shorter rod, 1,4-bis[trans-
(PEt3)2ClPd-CuC]-2,5-diethoxybenzene (6c), while the second one is associated with a longer rod, the
binuclear complex 1,4-bis[trans-(PEt3)2ClPd-4-(–CuC–C6H4–CuC)]-2,5-diethoxybenzene (7c). All new
compounds were characterized by NMR spectroscopy (1
H, 13C{1
H} and 31P{1
H}) as well as ESI-MS(TOF),
EA, FTIR, UV-Vis, cyclic voltammetry and solid-state photoluminescence. Our work shows the influence
of the alkoxy side chains on the electronic structure of the family of binuclear Pd rods by lowering its oxidation
potential. In addition to this, the increase of the length of the bridge results in a higher oxidation
potential. Solid state photoluminescence results indicate that Pd complexes are characterized by a
marked decrease in both the emission intensity and the fluorescence lifetime values as compared to their
ligands. This behaviour could be due to some degree of ligand-to-metal charge transfer. | |
