第一类拉链形人工双链体，由富电子的1，5-二氧基萘或1，4-二氧基苯与缺电子的均苯四酸二酰亚胺单元之间的多重供体-受体相互作用驱动，已在有机介质中通过H-1 NMR，UV-vis和蒸汽压渗透压法进行了研究。1H-1 NMR结合研究揭示了双链体中供体-受体相互作用的实质性协同性。
[GRAPHIC]The first class of zipper-shaped artificial duplexes, which are driven by multiple donor-acceptor interactions between electron-rich 1,5-dioxynaphthalene or 1,4-dioxybenzene and electron-deficient pyromellitic dimide units, have been studied in organic media by H-1 NMR, UV-vis, and vapor pressure osmometry. H-1 NMR binding investigations reveal substantial cooperativity of the donor-acceptor interaction in the duplexes.
