聚光捕胺——高灵敏胺响应型聚集诱导发光探针的合成及传感应用OA

This work bridges cutting-edge aggregation-induced emission(AIE)research with undergraduate education by developing an 8-hour comprehensive chemistry experiment.The laboratory exercise encompasses the synthesis and characterization of quinazoline derivatives 2-(2-hydroxyphenyl)quinazolin-4(3H)-one(HPQ)and 2-(2-(acetyl)phenyl)quinazolin-4(3H)-one(APQ),examination of HPQ's AIE characteristics,and evaluation of APQ's fluorescence response to amine vapors.The practical applications extend to invisible ink development and meat freshness detection.By demonstrating observable phenomena and real-world applications,this experiment effectively engages students'research interests while systematically developing their synthetic skills,characterization techniques,and scientific reasoning abilities,thereby enhancing both professional competency and innovative capacity.
