Nitration of 2-t-Butylpyrene and 2,7-di-t-butylpyrene leads to nitro derivatives which show an extremely weak interaction between the nitro group and the aromatic π-system; the orientation of the nitro group prevents this group from conjugation with the π-system, leading to an unperturbed pyrene electronic spectrum.
将2-叔丁基py和2,7-二叔丁基py硝化会生成硝基衍生物,该硝基衍生物显示出硝基与芳族π系统之间的相互作用非常弱。硝基的取向阻止该基团与π-系统共轭,导致pyr电子光谱不受干扰。
