Perhalogenated heteroaromatic systems, such as trichloro-s-triazine and pentafluoropyridine, are multifunctional "building blocks" that react with a number of appropriate difunctional nucleophiles to provide access to a variety of macrocyclic and even cage-like molecular architectures. Unusual structural and complexation characteristics of the systems reported so far, such as the recognition of anions, provide a further stimulus for the development of this area.
全卤代杂芳族体系，如三氯-s-三嗪和五氟吡啶，是多功能的“构建模块”，它们能与多种合适的双官能亲核试剂反应，从而构建出各种大环甚至笼状分子结构。目前报道的这类体系具有不同寻常的结构和络合特性，如对阴离子的识别，这为该领域的发展提供了进一步的推动力。
