The multistep syntheses of C-3-symmetrical tripodands with terminal triple bonds or azide groups exhibiting 1,3,5-triarylbenzene and 2,4,6-triaryl-1,3,5-triazine cores are reported herein. The structures of the newly synthesized compounds are supported by NMR investigations.

The synthesis of a 3-fold symmetric cofacial organic cage (COC) through Cu(I)-catalyzed azide–alkyne cycloaddition is reported. The COC can function as an efficient receptor for carcinogenic polycyclicaromatichydrocarbons to intercalate them in its intrinsic cavity through donor–acceptor and π···π stacking interactions. The association constants (Ka) are in the range of 3.7 × 104 to 1.3 × 106 M–1
据报道,通过Cu(I)催化的叠氮化物-炔烃环加成反应可合成3倍对称的有机界面有机笼(COC)。COC可以用作致癌多环芳烃的有效受体,通过供体-受体和π··π堆积相互作用将其插入其固有腔中。缔合常数(K a)在3.7×10 4到1.3×10 6 M –1的范围内。X射线衍射分析证明,多环芳烃(PAH)插入了COC内部。
