pentacene diester-dinitriles were synthesized. These pentacene derivatives underwent an unusual solidstate [4 + 4] thermal dimerization with good efficiency and complete stereoselectivity. This observation indicates this series of pentacene derivatives adopt π–π stacking geometry with large mutual overlap in solidstate. This notion was confirmed by molecualr dynamic simulation.

A series of novelcationicfumaricpolymerizableemulsifiers (named as F seriesemulsifiers) were synthesized. The chemical structures of these emulsifiers were confirmed by 1H NMR and MS and their minimal inhibitory concentrations to Escherichia coli were determined. Antibacterial tests of latex films showed that [2‐(N‐benzyl‐N,N‐dimethylamino)ethyl]dodecyl fumaric ammonium bromide, [2‐(N‐benzyl‐N
合成了一系列新型的阳离子富马酸可聚合乳化剂(称为F系列乳化剂)。这些乳化剂的化学结构通过1 H NMR和MS确认,并确定了它们对大肠杆菌的最小抑菌浓度。乳胶薄膜的抗菌测试表明,[2-(N-苄基-N,N-二甲基氨基)乙基]十二烷基富马酸溴铵,[2-(N-苄基-N,N-二甲基氨基)乙基]癸基富马酸氯化铵和[ 2‐(N‐苄基‐ N,N-二甲基氨基)乙基]十二烷基富马酸氯化铵可用作可聚合的杀菌剂。

A process for preparing proponates which comprises the steps of (i) supplying a solution of methanol containing 4-hydroxyphenylmethylcarbinol, (ii) subjecting said solution to an acid catalyzed displacement reaction for a sufficient period of time and under suitable conditions of temperature and pressure to convert substantially all of said carbinol to 4-hydroxyphenylmethylcarbinol methyl ether in solution, (iii) replacing the methanol in said ether containing solution with a second solvent and (iv) reacting the ether containing ethyl lactate solution with a suitable acid catalyst for a sufficient period of time and under suitable conditions of temperature and pressure to form said propanoates. New compositions of matter which comprise the propanoates, prepared in the above manner, have application in the electronic chemicals market such as in a photoresist composition.
