  Spectroscopic study on the photophysical properties of novel lanthanide complexes with long chain mono-L phthalate (L=hexadecyl, octadecyl and eicosyl)

  摘要：

  Ortho-phthalic anhydride was modified with long chain alcohol (1-hexadecanol, I-octadecanol and 1-eicosanol) to their corresponding mono-L phthalate (L=hexadecyl, octadecyl and eicosyl), i.e. monohexadecyl phthalate (16-Phth), monooctadecyl phthalate (18-Phth), and monoeicosyl phthalate (20-Phth), respectively. Nine novel lanthanide (Eu3+, Tb3+ and Dy3+) complexes with these three mono-L phthalate ligands were synthesized and characterized by elemental analysis and IR spectra. The photophysical properties of these complexes were studied in detail with various spectroscopes such as ultraviolet-visible absorption spectra, low temperature phosphorescence spectra and fluorescent spectra. The ultraviolet-visible absorption spectra show some band shifts with the different chain-length of phthalate monoester and homologous lanthanide complexes. From the low temperature phosphorescent emission, the triplet state energies for these three ligands were determined to be around 22,650 cm(-1) (16-Phth), 23,095 cm(-1) (18-Phth) and 22,400 cm(-1) (20-Phth), respectively, suggesting they are suitable for the sensitization of the luminescence of Eu3+, Tb3+ and Dy3+. The fluorescence excitation and emission spectra for these lanthanides complexes of the three ligands take agreement with the above predict from energy match. (c) 2004 Elsevier B.V.

• Fabrication and spectroscopic properties of Langmuir–Blodgett films of novel zinc complexes with long chain mono (hexadecyl, octadecyl, eicosyl, and docosyl) phthalate

  In this paper, some novel long chain amphiphillic monoester molecules were designed to afford double functions: film-formation and luminescent sensitization. Subsequently, organized molecular films of zinc complexes with these functional ligands formulated as ZnL2 were fabricated by the Langmuir-Blodgett film (LB) technology, where L denoted the long chain carboxylic ligands monohexadecyl phthalate (16-Phth), monooctadecyl plithalate (18-Phth), monoeicosyl phthalate (20-Phth) and monodocosyl plithalate (22-Phth). The average molecular area was obtained according to the pi-A isotherms. The layer structure of the LB films was demonstrated by low-angle X-ray diffraction and the average layer spacing were obtained according to the Bragg equation. The characteristic luminescence behaviors of LB films have been discussed compared with those of their corresponding solid complexes. (C) 2007 Elsevier B.V. All rights reserved.
