Synthesis of Aminolaurylpyridinium Chloride as Antimicrobial Agent

4-amino-laurylpyridinium chloride （ALPC） was synthesized and employed in antimicrobial finishing of wool fabrics. The structures of the salt was fully characterized by using FTIR, 1 H-N-MR and ^13C-NMR analysis. The effects of pH conditions of finishing baths, finishing time and temperature, and salt concentrations were investigated. ALPC could form ionic interactions with anionic groups on wool, which contribute to durable antimicrobial functions. The finished wool fabrics exhibited antimicrobial efficacy against Escherichia coll. The washing durability of antimicrobial functions on the finished wool fabrics was also studied.

八元瓜环对1,ω-二(2-氨基吡啶)烷烃光致环加成反应的超分子催化性能的研究

合成了三种不同链长的1,ω-二(2-氨基吡啶)烷烃,分别为二溴化1,4-二(2-氨基吡啶)丁烷(C4)、二溴化1,6-二(2-氨基吡啶)己烷(C6)、二溴化1,8-二(2-氨基吡啶)辛烷(C8).考察了八元瓜环(Q[8])与上述三种1,ω-二取代烷烃的主客体相互作用,运用1H NMR及UV-vis证明三种客体与Q[8]的作用模式均不相同.在此基础上,考察了八元瓜环对三种底物光致环加成反应的超分子催化性能.结果表明,由于三种底物与Q[8]的主客体作用模式不同,八元瓜环对它们光二聚反应的超分子催化性能也各有差异.

七、八元瓜环对N-烯丙基-2-氨基吡啶光致环加成反应的选择性催化研究

选择N-烯丙基-2-氨基吡啶(NPAP+)作为底物,利用荧光光谱、1H NMR技术等方法考察了七、八元瓜环与NPAP+的相互作用,并探讨了七、八元瓜环对NPAP+发生光致环加成的反应位点、产物的立体选择性,以及动力学性质.结果表明七、八元瓜环与NPAP+可形成1∶1的配合物,并对NPAP+发生光致环加成反应产物的结构有选择性催化作用.
