酞菁(铜-PCs)1-3和In~(3+)-卟啉4和5衍生物通过π电子相互作用(π-π相互作用)与富含π-π电子的化合物，如多环芳烃(PAH)相互作用。它们对分离π富电子化合物很有用，尽管它们的制备需要麻烦的步骤1-5另一方面，我们简要地报告了阴离子铜-π-π通过静电和疏水相互作用很容易结合在普通阴离子交换树脂上，并且改性树脂与多环芳烃表现出相对较强的高效液相色谱相互作用。6然而，改性树脂不完全适合于用于分析目的的高效液相色谱固定相，因为由于树脂的不规则粒度，理论板数(N)相对较低。为了开发一种新的高效液相固定相，我们尝试用CuPCS对一种阴离子交换树脂进行改性。因此，我们可以通过一种简单的铜修饰方法来增加疏水相互作用，包括高效阴离子交换树脂对大分子多环芳烃的π-π相互作用。在本文中，我们报告了合成的改性树脂作为分离富含π电子的多环芳烃的高效液相固定相的性质。
phthalocyanine (Cu-PCS)1–3 and In3+-porphine4 and pyrene5 derivatives interact with π-electron-rich compounds, such as polyaromatic hydrocarbons (PAHs), through a π-π electron interaction (π-π interaction). They are useful for separating πelectron-rich compounds, although their preparation requires troublesome procedures.1–5 On the other hand, we have briefly reported that anionic Cu-PCS are easily bound on an ordinary anion-exchange resin through electrostatic and hydrophobic interactions, and that the modified resin exhibits a relatively strong π-π interaction with PAHs.6 However, the modified resin was not completely suited for an HPLC stationary phase for an analytical purpose, because the theoretical plate number (N) is relatively low due to the irregular particle size of the resin. To develop a new HPLC stationary phase, we thus tried to modify an HPLC anion-exchange resin for HPLC with CuPCS. Consequently, we could increase hydrophobic interactions, including the π-π interaction of an HPLC anionexchange resin for large PAHs by an easy modification method with Cu-PCS. In the present paper, we report on the properties of the resultant modified resin as the HPLC stationary phase for the separation of π-electron-rich PAHs.
