Abstract
The effect of the central metal of columns packed with silica gels binding Ni 2+ - and Cu 2+ -phthalocyanine derivatives (Ni-and Cu-PCS D s) on the retention behavior of poly-aromatic-hydrocarbons (PAHs) thereof in a polar eluent was examined. The retention factors of PAHs on the Ni- and Cu-PCS D s in 80% methanol showed a good linear correlation. The Cu-PCS D column exhibited the π-π interactions for PAHs, while the Ni-PCS D column exhibited the π-d interactions for PAHs in addition to the π-π interaction for PAHs. Further, an investigation of the retention behavior of anthracene derivatives having different substituents revealed that the Ni- and Cu-PCS D columns could recognize the differences of substituents only in a polar eluent. 2006
