We have developed a synthetic strategy to selectively incorporate the imidazole ring into the 1,1′-bi-2-naphthol (BINOL) skeleton at the different position. The resulting conformationally rigid BINOL-based diimidazolyl ligands bearing both hydrogen-bond-acceptors and -donators can self-assemble into homochiral channel-like mono-component organic frameworks via intermolecular O–H⋯N hydrogen bonds between the phenolic hydroxyl group and the N2 or N4 atom of the imidazole ring.
我们开发了一种合成策略,在 1,1′-双-2-萘酚(BINOL)骨架的不同位置选择性地加入咪唑环。由此产生的构象刚性 BINOL 基二咪唑配体同时具有氢键受体和氢键供体,可通过酚羟基与咪唑环 N2 或 N4 原子间的分子间 O-H⋯N 氢键自组装成同手性通道状单组份有机框架。
