[2.2]Paracyclophane (pCp) scaffolds, unlike many π-conjugated building blocks, have been rarely explored in supramolecular self-assembly. Herein we report the synthesis and characterization of two ligands, pCpd3py and pCpd4py, composed of a pCp core functionalized at its 7- and 15-positions respectively with 3-pyridyl and 4-pyridyl units. The self-assembly of pCpd4py with Pd2+ metal ions afforded a [Pd3(pCpd4py)6]6+ cage structure, pCpd4py-Pd, where the six pCpd4py ligands doubly bridge each edge of the Pd3 triangular core. The ligand pCpd4py and the palladium cage pCpd4py-Pd have been characterized by NMR spectroscopy, ESI-MS spectrometry and X-ray diffraction analyses and their photophysical properties investigated by steady-state and time-resolved emission spectroscopy as well as time-dependent density functional theory calculations.

一个Pd 3 L 6超分子笼,结合了光敏[2.2]对环烷单位†
[2.2]与许多π共轭结构单元不同,泛环(pCp)支架很少在超分子自组装中得到研究。本文中,我们报道了两个配体pCpd3py和pCpd4py的合成和表征,这两个配体由在7和15位分别被3-吡啶基和4-吡啶基官能化的pCp核组成。pCpd4py与Pd 2+金属离子的自组装提供了[Pd 3(pCpd4py)6 ] 6+笼状结构pCpd4py-Pd,其中六个pCpd4py配体双桥了Pd 3三角芯的每个边缘。配体pCpd4py并通过NMR光谱,ESI-MS光谱和X射线衍射分析对钯笼pCpd4py-Pd进行了表征,并通过稳态和时间分辨发射光谱以及随时间变化的密度泛函理论计算研究了它们的光物理性质。
