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).

• 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。
