Synthesis and Characterization of Octylthio-Metallophthalocyanines: Effect of Various Kinds of Metal Coordination on Their Spectroscopic and Magnetic Properties

초록

The octylthio phthalocyanines with Ni, Cu, Co and Zn central metal ions were synthesized and characterized. The B(Soret) and Q band of NiPc are more blue-shifted than the other MPcs due to stronger electronegativity (E-N/r(l)) of the nickel central metal ion. In addition, the strong fluorescence peak of ZnPc was obtained due to fully occupied d-orbital electronic configuration of Zn2+(d(10)). The EPR data shows that Cu and Co complex has broad peaks and the g value of octylthio CoPc increases as the temperature decreases because of the efficient spin-orbital coupling of the unpaired electron at the lower temperature.
