Structures of phenol-ammonia and phenol-water compounds

Phenol-water and phenol-ammonia clusters are useful model systems for understanding the types of proton-transfer interactions that occur during photosynthesis in plants and bacteria. However, almost nothing is known about these complexes in the solid state. Since these appear to be excellent candidates to undergo solid-state proton transfer under slight degrees of compression, structure determinations at low temperature and later under hydrostatic pressure are required. The aim of this work is to carry out low-temperature structural characterisation of the known phases, phenol hemihydrate, phenol mono-ammoniate and phenol di-ammoniate. Furthermore, I propose to evaluate the possible existence of an ammonia-rich phase with a phenol to ammonia ratio of about 9:1.

苯酚(Phenol)-水团簇与苯酚-氨团簇是解析植物与细菌光合作用过程中质子转移相互作用类型的理想模型体系。然而，目前针对这类固态复合物的相关研究几乎空白。鉴于这类团簇在轻度压缩条件下是发生固态质子转移的极佳候选体系，因此需开展低温环境及后续静水压环境下的结构测定工作。本研究的目标为对已知晶相——苯酚半水合物、苯酚单氨合物与苯酚二氨合物开展低温结构表征。此外，本研究还将探究苯酚与氨摩尔比约为9:1的富氨晶相是否存在。
