terminal double bond meaning in English
末端变键
末端双键
Examples
- First , a terminal double bond was introduced into 3 - amino - 9 - ethylcarbazole ( aec ) via methacryloyl chloride to obtain the compound , 3 - ( n - methacryloyl ) amino - 9 - ethylcarbazole ( mec ) . second , mec was copolymerized with butyl methacrylate to prepare the mec - immobilized polymer particles . the resultant polymer particles were used as a fluorescence probe , which was almost free of dye leaching , and had higher photostability in comparison with free aec
首先利用甲基丙烯酰氯向3 -氨基- 9 -乙基咔唑( aec )分子中引入末端双键,得到带末端双键的荧光指示剂3 - ( n -甲基丙烯酰基)氨基- 9 -乙基咔唑( mec ) ,然后通过乳液聚合技术将mec共价固定到聚甲基丙烯酸丁酯基体上,制得一种共价固定了mec的聚合物颗粒。 - In this thesis , several new fluorescence carriers have been synthesized bearing a carbon chain with a terminal double bond introduced into the molecule and copolymerized with a monomer under uv irradiation on the silanized glass or quartz disk . the sensors prepared were studied . covalent immobilization effectively prevents the leakage of the carrier dye from the sensor membrane , a phenomenon that shortens the lifetime of ordinary optical sensors
本论文合成了几种含末端双键、可共价固定的新型荧光化合物，并以此作为荧光指示剂，与膜基质单体在光引发剂作用下发生光聚反应共聚在经过硅烷化处理的石英或普通玻片上制成光极膜，制备了对一些物质有响应的荧光化学传感器。
