A linear molecular architecture equipped with complementary three‐fold hydrogen‐bonding units embedded with a photoswitchable trans‐tetrafluoroazobenzene moiety was synthesized. The transto cis photoisomerism of the azobenzene unit induced drastic changes in the molecular architecture as a result of intramolecular hydrogen bonding as evidenced by NMR spectroscopy and size exclusion chromatography. A
合成了线性分子结构,该结构配备了嵌入有可光转换的反式-四
氟偶氮苯部分的互补三
重氢键单元。NMR光谱法和尺寸排阻色谱法证明,由于分子内氢键,
偶氮苯单元的反式至顺式光异构现象引起分子结构的急剧变化。线性反式状态中的微小立体成因元素使立体选择性折叠成顺式,从而产生具有增强的手性的球形结构。
