Abstract

A mild and highly selective hydrosilylation method was employed to synthesize five novel well-defined Janus ring siloxanes bearing terpenes and terpenoids, which are the main bioactive components of essential oils. The characterization of these new bio-sourced molecular materials, derived from hydrosilyl-substituted all-cis-cyclotetrasiloxane, was conducted through comprehensive analyses using multinuclear NMR, infrared spectroscopy, elemental analysis, and mass spectroscopy. The thermal stability of the newly synthesized Janus rings was investigated, and the siloxane skeleton was shown to confer an enhanced thermal stability compared with free terpenes and terpenoids.

含有萜烯和萜类化合物的生物基詹纳斯环硅氧烷的合成与热性能。

研究人员采用温和、高选择性的氢硅烷化方法合成了五种新型的定义明确的 Janus 环硅氧烷，这些硅氧烷含有萜烯和萜类化合物，而萜烯和萜类化合物是精油的主要生物活性成分。通过使用多核核磁共振、红外光谱、元素分析和质谱进行综合分析，对这些由氢硅烷取代的全顺式环四硅氧烷衍生的新型生物源分子材料进行了表征。对新合成的 Janus 环的热稳定性进行了研究，结果表明与游离萜烯和萜类化合物相比，硅氧烷骨架具有更强的热稳定性。

期刊介绍： Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
