Abstract
With the aim of studying the optical, electrochemical, and electronic properties of a new porphyrin-based material, we have synthesized a new porphyrinic complex, namely the (4,4 '-bipyridine)(meso-tetratrifluoromethylphenylporphyrinato)zinc(II) 4,4 '-bipyridine disolvate dihydrate complex with the formula [Zn(TFMPP)(4,4 '-bipy)]center dot 2(4,4 '-bipy)center dot 2H(2)O (I). This species is characterized by single-crystal X-raymolecular structure. The optical study is performed by UV-visible absorption and fluorescence spectroscopy. The fluorescence intensity presents an emission in the UV-visible range, indicating that this compound can be used as an optoelectronic material. The optical energy gap is 1.95 eV, and the current-voltage characteristics and impedance spectroscopy measurements have been studied to define the electronic properties of the zinc (II) porphyrin complex. The barrier height phi(b) is calculated, and the space-charge limited current mechanism is found to control the conductance. The results from the electronic study confirm that our porphyrin derivative can be used for various optoelectronic applications.
