以FeCl（3）为催化剂，不同的1，4-二烷氧基苯和多聚甲醛为原料，合成了共聚[5]芳烃，产率为50-85%。用1H NMR和X射线衍射研究了（共）柱[5]芳烃和端二溴烷烃的主-客体性质。通过改变主体上的取代基可以调节共柱[5]芳烃的络合行为。在柱[5]芳烃和柱[6]芳烃之间发现了完全的络合选择性，这是传感器技术的一个有趣的方面。
An efficient method for the synthesis of copillar[5]arenes was developed with FeCl(3) as catalyst and different 1,4-dialkoxybenzenes and paraformaldehyde as reactants (yields: 50-85%). The host-guest property of (co)pillar[5]arenes and terminal dibromoalkanes was investigated by (1)H NMR measurements and an X-ray study. The complexation behavior of the copillar[5]arenes can be tuned by changing the substituents on the host. A complete complexation selectivity was found between pillar[5]- and pillar[6]arenes, which is an interesting aspect for sensor techniques.
