[5,10,15,20-Tetrakis(4-decaneoxyphenyl)-β-nitro-porphyrinato]nickel(II) (1) and {5,10,15,20- tetrakis(4-decaneoxypheny1)-6 -nitroquinoxalino[2,3-b ]porphyrinato}nickel(II) (2) are synthesized and confirmed by 1H NMR, infrared spectroscopy, mass spectrometry (MS), and elemental analysis. The first oxidation potentials of 1 and 2 are positive-shifted and the maximum absorptions of 1 and 2 are red-shifted compare with those of starting compound 3. Differential scanning calorimetry (DSC) results show that only compound 1 possesses liquid crystal property, which behaves the heating monotropic liquid crystal. The self-assembly films of the compounds on Si are studied by atomic force microscopy (AFM), the self-assembly film of 1 is better ordered compared with that of 2. These results indicate that the different physical properties of compounds 1 and 2 are mainly due to their different β-substituted groups. The observed electronic properties are explained by calculated results based on density functional theory (DFT).

Key words: porphyrin, cyclic voltammetry, liquid crystal, self-assembly, density functional theory (DFT)
