Abstract
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.
