The effective application of biocidal species requires building the active moiety into a molecular back bone that can be delivered and decomposed on demand under conditions of low pressure and prolonged high-temperature detonation. The goal is to destroy storage facilities and their contents while utilizing the biocidal products arising from the released energy to destroy any remaining harmful airborne agents. Decomposition of carefully selected iodine-rich compounds can produce large amounts of the very active biocides, hydroiodic acid (HI) and iodine (I2). Polyiodide anions, namely, I3(-), I5(-), which are excellent sources of such biocides, can be stabilized through interactions with large, symmetric cations, such as alkyl ammonium salts. We have designed and synthesized suitable compounds of adaptable high density up to 3.33 g cm(-3) that are low-pressure polyiodides with various alkyl ammonium cations, deliverable iodine contents of which range between 58.0-90.9%.
生物杀灭剂的有效应用需要将活性部分构建到分子主链中，该分子主链能够在低压和长时间高温爆炸条件下按需递送并分解。目标是摧毁储存设施及其所含物品，同时利用释放能量产生的生物杀灭产物来消灭任何残留的有害空气传播媒介。精心挑选的富碘化合物分解可产生大量活性很强的生物杀灭剂氢碘酸（HI）和碘（I₂）。多碘阴离子，即I₃⁻、I₅⁻，是此类生物杀灭剂的优质来源，可通过与大型对称阳离子（如烷基铵盐）相互作用实现稳定。我们已经设计并合成了密度高达3.33 g·cm⁻³的合适化合物，它们是具有各种烷基铵阳离子的低压多碘化物，可递送的碘含量在58.0 - 90.9%之间。
