This work reports on photophys. properties of the non-peripherally and peripherally substituted Zn phthalocyanines (Pcs) prepared by two different synthetic routes. Tetra-substituted non-peripheral and peripheral Zn phthalocyanines containing 4-mercaptophenol groups were synthesized from novel phthalonitrile derivatives for the 1st time. Pyrene-containing phthalocyanine derivatives were obtained by the reaction of these compounds with 1-bromoacetylpyrene. In the 2nd route, the pyrene-containing phthalocyanine derivatives were prepared by cyclotetramerization of pyrene-containing phthalonitrile derivatives The synthesized compounds were characterized by elemental anal., FTIR, UV-visible, NMR spectroscopy and mass spectra. General trends were described for electronic absorption, fluorescence quantum yields, lifetimes, and fluorescence quenching by benzoquinone of these compounds The effects of position of substituent on photophys. properties of the tetra-substituted Zn Pcs were also studied. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Safety of 2-Bromo-1-(pyren-1-yl)ethanone).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
