Synthesis, spectral and photophysical investigation of porphyrazines with eight 3-quinolinecarboxy esters

Abstract

In this study, the syntheses and characterization of [2,3,7,8,12,13,17,18-octakis [2′-(3-quinolincarboxy)ethylhio] porphyrazinato N²¹N²²N²³N²⁴] magnesium(II), quaternized [2,3,7,8,12,13,17,18-octakis [2′-(3-quinolincarboxy)ethylhio] porpyrazinato N²¹N²²N²³N²⁴] magnesium(II), [2,3,7,8,12,13,17,18-octakis[2′-(3-quinolinecarboxy)-ethylthio]21H23H N²¹N²²N²³N²⁴ porphyrazine and [2,3,7,8,12,13,17,18-octakis[2′-(3-quinolinecarboxy)-ethylthio]porphyrazinato N²¹N²²N²³N²⁴} zinc are described. The new compounds have been characterized by elemental analysis, FT-IR, ¹H-NMR, and mass spectra. General trends are described for fluorescence quantum yields of these compounds in dimethylsulfoxide (DMSO). In this study, the effects quaternization of the substituents on the photophysical and spectroscopic properties are also reported.
