A new class of porphyrin array was synthesized. The Cu(II) porphyrin-PAMAM-Cu(II) porphyrin was obtained in good yields. The EPR studies showed that all porphyrins obtained have signals of a copper complex with planar geometry, and no variation in the tetrahedral distortion of the porphyrin ring was observed. The UV-vis and emission studies showed that the intensity of the signal increased due to the presence of 5 porphyrin moieties in the structure. In order to further characterize this molecule, thin films were prepared by using the thermal evaporation method. The morphology of the film showed a homogeneous structure while conductivity measurements exhibit a good conductive response.
