Two novel series of fluorinated and non-fluorinated bisphenoxy benzyl ether with cyano/pentyl terminal groups zinc(II) phthalocyanines were synthesized. Their structures were characterized by elemental anal., IR, 1H NMR, 13C NMR, ESI-MS and MALDI-TOF-MS methods. The photophys. properties, photoinduced intramol. electron transfer, and photoinduced intramol. energy transfer of fluorinated and non-fluorinated phthalocyanines were compared by UV-Vis and fluorescence spectroscopic methods. These properties exhibited fluorinated substituents and terminal groups nature dependence. Fluorinated zinc(II) phthalocyanine with pentyl ester terminal groups had the highest molar absorption coefficient, fluorescence intensity and fluorescence lifetime. Non-fluorinated zinc(II) phthalocyanine with cyano terminal groups exhibited the highest energy transfer efficiency. In addition to this study using 4-Cyanobenzyl bromide, there are many other studies that have used 4-Cyanobenzyl bromide(cas: 17201-43-3Electric Literature of C8H6BrN) was used in this study.
4-Cyanobenzyl bromide(cas: 17201-43-3) is used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile. It is also useful in the preparation of 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile by reaction with 2H-tetrazole in the presence of potassium hydroxide.Electric Literature of C8H6BrN
