The photochemical and electrochemical properties of chiral porphyrin dimer and self-aggregate nanorods of cobalt(II) porphyrin dimer

In this paper, the novel chiral porphyrin dimer ligand and its cobalt(II) porphyrin dimer were synthesized by using a glutamate bridging group. The FT-IR and Raman spectra of the chiral porphyrin dimer were investigated. Furthermore, the photochemical and electrochemical properties of dimer were studied. In addition, we prepared the nanorods of the cobalt(II) porphyrin dimer using liquid-solid-solution (LSS) technologies. The shape and dimension of the spontaneous aggregates of cobalt(II) porphyrin dimer were characterized by the transmission electron microscopy (TEM). The results show the diameter and shape of the aggregates can be controlled by refining the stocked solution temperature.
