  摘要：

  最近有报道称树枝状苝 3,4:9,10-四羧酸双酰亚胺 (PBI), (3,4,5)12G1-3-PBI 可在含有 PBI 四聚体作为基本重复单元的复杂螺旋柱中自组装. 这些四聚体包含一对并排排列的两个分子，另一对在柱的下一层中颠倒并围绕柱轴旋转。四聚体内和四聚体间的旋转角度和堆叠距离是不同的。在高温下，(3,4,5)12G1-3-PBI 通过热力学控制过程在 2D 六角柱状相中自组装，而在低温下通过动力学控制过程在 3D 正交柱状阵列中自组装。在这里，我们通过差示扫描量热法、X 射线和电子衍射的组合报告了合成和结构分析，和固态核磁共振在不同温度下对由 (3,4,5)nG1-3-PBI 库生成的超分子结构进行，n = 14-4。对于 n = 11-8，来自低温的动力学控制自组装在热力学控制过程中发生变化，而 n = 9 和 8 的正交柱状阵列从热力学产物转变为动力学产物。n = 9, 8

  Synthesis and Retrostructural Analysis of Libraries of AB₃ and Constitutional Isomeric AB₂ Phenylpropyl Ether-Based Supramolecular Dendrimers

  摘要：

  We report the synthesis of methyl esters of 3-(4-hydroxyphenyl)propionic, 3-(3,4-dihydroxyphenyl)propionic, 3-(3,5-dihydroxyphenyl)propionic, and 3-(3,4,5-trihydroxyphenyl)propionic acids and their use in a convergent iterative strategy to prepare up to four generations of three libraries, one of 3,4,5- and two of constitutional isomeric 3,4- and 35-substituted 3-phenylpropyl dendrons. Each library contains 3-[3,4,5-tris(dodecyl-1-oxy)phenyl]propyl-, 3-[3,4-bis(dodecyl-1-oxy)phenyl]propyl-, 3,4-bis[3-(4-dodecyl-1-oxyphenyl)propyl-1-oxy]phenyl-1-propyl-, and 3-13,4,5-tris[3-(4-dodecyl-1-oxyphenyl)propyl-1-oxy]phenyllpropyI ether first-generation clendrons on their periphery and -CO2CH3, -COOH, and -CH2OH groups at their apex. Regardless of their generation number and their periphery, internal, and apex structures, these dendrons self-assemble into supramolecular dendrimers that self-organize into all periodic and quasi-periodic assemblies encountered previously and in several unencountered with architecturally related benzyl ether-based supramolecular dendrimers. A variety of porous columnar lattices that were previously obtained only from clendritic dipepticles and hollow supramolecular spheres were also discovered from these building blocks. The more flexible and less compact 3-phenylpropyl ether repeat units are stable under acidic conditions, facilitate a simpler synthetic strategy, provide faster dynamics of self-assembly into higher-order supramolecular structures of larger dimensions, exhibit lower transition temperatures than the corresponding benzyl ether homologues, and demonstrate the generality of the self-assembly concept based on amphiphilic dendrons.

  tetrachlorinated perylene bisimide (Cl4PBI) was functionalized with two AB3 minidendrons containing hydrogenated or semifluorinated dodecyl groups. The hydrogenated dendron was attached to the imide groups of Cl4PBI via m = 0, 1, and 2 methylenic units, whereas the dendron containing semifluorinated groups was attached via m = 3 or a di(ethylene oxide) linker (m = 2EO). The supramolecular structures of these

  Simple synthetic methods for a strongly electron-accepting naphthalene bisimide (NBI) derivative functionalized with a new environmentally friendly chiral racemic semifluorinated alkyl group and with AB(3) minidendrons containing the same semifluorinated group are reported. The semifluorinated dendron was attached to the imide groups of the NBI via one, two, and three (m = 1, 2, 3) methylenic units. The NBI-containing semifluorinated groups and the dendronized NBI with m = 1 and 2 self-organize into lamellar crystals. The dendronized NBI with m = 3 self-assembles into an unprecedentedly complex and ordered column that self-organizes in a columnar hexagonal periodic array. This array undergoes a continuous transition to a columnar hexagonal superlattice that does not display a first-order phase transition during analysis by differential scanning calorimetry at heating and cooling rates of 10 and 1 degrees C/min. These complex columnar hexagonal periodic arrays with intramolecular order could be elucidated only by a combination of powder and fiber X-ray diffraction studies and solid-state NMR experiments. The lamellar crystals self-organized from m = 1 and the two highly ordered columnar hexagonal periodic arrays of m = 3 are assembled via thermodynamically controlled processes. Since strongly electron-accepting derivatives are of great interest to replace fullerene acceptors in organic photovoltaics and for other supramolecular electronic materials, the multitechnique structural analysis methodology elaborated here must be taken into consideration in all related studies.
