Sequence-defined polymers with customizable sequences, monodispersity, substantial length, and large chemical diversity are of great interest to mimic the efficiency and selectivity of biopolymers. We report an efficient, facile, and scalable synthetic route to introduce many chemical functionalities, such as amino acids and sugars in nucleic acids and sequence-controlled oligophosphodiesters. Through achiral tertiary amine molecules that are perfectly compatible with automated DNA synthesis, readily available amines or azides can be turned into phosphoramidites in two steps only. Individual attachment yields on nucleic acids and artificial oligophosphodiesters using automated solid-phase synthesis (SPS) were >90% in almost all cases. Using this method, multiple water-soluble sequence-defined oligomers bearing a range of functional groups in precise sequences could be synthesized and purified in high yields. The method described herein significantly expands the library of available functionalities for nucleic acids and sequence-controlled polymers.
Oil soluble molybdenum amine complex and preparation method thereof

Paragraph 0052, (2017/07/19)
The invention discloses an oil soluble molybdenum amine complex and a preparation method of the oil soluble molybdenum amine complex. The method adopts long-chain saturated fatty acid as the starting material, acylchlorination reaction is carried out on the long-chain saturated fatty acid and thionyl chloride to obtain 1-chloro saturated fatty acid, then amidation reaction is carried out on the 1-chloro saturated fatty acid and diethanol amine to obtain saturated fatty acid amide, and finally complexation is carried out on the saturated fatty acid amide and a molybdenum trioxide solution so as to obtain the oil soluble molybdenum amine complex. The prepared molybdenum amine complex has good oil solubility, solves the poor oil solubility, corrosion resistance, wear resistance and friction reduction and other problems difficult to overcome in existing products, at the same time significantly reduces the adding amount of high sulfur and phosphorus components, and has enormous boosting effect on organic molybdenum series lubricating products currently under research in China, thus promoting nationalization of high-end lubricating oil and efficient utilization and high added value of molybdenum resources.

Diethanolamides are nonionic emulsifiers widely used in industries such as cosmetics and as corrosion inhibitors. Candida antarctica lipase (Novozym 435) was used to catalyze the amidation of various fatty acids with diethanolamine. Contents of fatty acid
