We report the preparation and X-ray crystallographic characterization of the first crystalline homoatomic polymer chain, which is part of a semiconducting pyrroloperylene-iodine complex. The crystal structure contains infinite polyiodide I∞ (δ-) . Interestingly, the structure of iodine within the insoluble, blue starch-iodine complex has long remained elusive, but has been speculated as having infinite chains of iodine. Close similarities in the low-wavenumber Raman spectra of the title compound and starch-iodine point to such infinite polyiodide chains in the latter as well.
我们报告了首例同原子聚合物链的制备和 X 射线晶体学表征，该聚合物链是一种半导体吡咯并[3,4-c]吡咯-碘络合物的一部分。晶体结构包含无限长的多碘化物 I∞（δ-）。有趣的是，在不溶性的蓝色淀粉-碘络合物中碘的结构长期以来一直难以捉摸，但人们推测它具有无限长的碘链。标题化合物和淀粉-碘的低波数拉曼光谱非常相似，表明后者也存在这种无限长的多碘链。
