A new hierarchical self-assembling molecular template, which can size-selectively immobilize fullerene molecules, is reported. The molecular template is fabricated from 1,3,5-tris(10-carboxydecyloxy)benzene (TCDB) and triangle-shaped macrocycles. It is observed that the two-dimensional hydrogen-bonded achiral TCDB network affected by the 3NN-Macrocycle becomes a chiral network. Host and guest molecules both form chiral arrangements with hexagonal empty pores. In addition, fullerenes and other molecules such as coronene can be entrapped in the empty pores or on the 3NN-Macrocycle molecules. The adsorption constant (K) is estimated, from which it is concluded that the different filling behaviors of the fullerenes are associated with the different sizes of the guest species. This method provides a facile approach to molecularly designed surfaces and the study of fullerene molecular arrays on the single-molecule level.
报道了一种新的分级自组装分子模板，它可以选择性地固定富勒烯分子。该分子模板由 1,3,5-三(10-羧基癸氧基)苯（TCDB）和三角形大环制成。观察到二维氢键非手性 TCDB 网络受 3NN-大环的影响变成手性网络。主体和客体分子都形成具有六边形空孔的手性排列。此外，富勒烯和其他分子，如蒄，可以被包埋在空孔或 3NN-大环分子中。估计了吸附常数（K），从中可以得出结论，富勒烯的不同填充行为与客体分子的不同尺寸有关。这种方法为分子设计表面和在单分子水平上研究富勒烯分子阵列提供了一种简便的方法。
