  Development of Functionalized Cyclotriveratrylene Analogues: Introduction of Withdrawing and π-Conjugated Groups

  摘要：

  Cyclotriveratrylene analogues (CTVs) are supramolecular bowl-shaped molecules known for their ability to complex organic and organometallic guests, to form liquid crystals, polymers, or nanostructures. In this Article, we report the synthesis of new cyclotriveratrylene analogues with fluorescence properties in which various electron-withdrawing or pi-extended conjugated groups are appended to the wide rim ortho to the methoxy-donating groups. Synthetically, these functionalized CTVs cannot be obtained as CTVs with electron-rich functions by the typical method (i.e., the trimerization of the corresponding benzyl alcohol) but are prepared from a common key intermediate, the C-3-triiodocyclotriveratrylene (CTV-I-3), in good yields. Despite the synthetic difficulties encountered due to the presence of three reactive centers, we have demonstrated the possibility of performing Sonogashira coupling and Huisgen cycloaddition reactions directly to the CTV core for the first time. CTVs with pi-extended conjugated groups reveal interesting fluorescence profiles. More broadly, this study utilizes CTV-I-3 to introduce novel functionalities into CTVs to keep exploring their potential applications.

  allowed us to detect the complexes as proton adducts. The intensities of the signals were stronger when the phosphine was more electron-rich. This technique was also used to investigate the exchange of phosphine betweeen pairs of CTB complexes. The scrambling reaction was demonstrated by the higher intensity of the signals of the complexes subjected to the exchange of a single phosphine ligand by comparison

  合成了外消旋和对映体纯形式的两种不同的炔基取代的C 3对称环三亚苄基 (CTB)，并制备并表征了六种金 ( I ) 膦络合物（CTB 和膦的性质不同），特别是通过 NMR 光谱进行表征、DOSY、电子圆二色性 (ECD) 和电喷雾电离质谱 (ESI-MS)。它们的 ECD 模式取决于起始 CTB 的替换，并且与后者相比发生红移。 HCO 2 H 存在下的 ESI-MS 使我们能够将复合物检测为质子加合物。当磷化氢富含电子时，信号强度更强。该技术还用于研究 CTB 复合物对之间磷化氢的交换。与起始复合物的信号强度相比，经过单一膦配体交换的复合物的信号强度更高，证明了加扰反应。
