摘　　要：电化学发光(ECL)兼备电化学和化学发光的特点,灵敏度高、线性范围宽、背景干扰小,得到了广大分析科学研究者的关注;传统的ECL材料虽然发光效率高,但仍存在价格昂贵、负载量低等缺点。g-C_(3)N_(4)是一种不含金属的半导体纳米材料,主要以三嗪环或七嗪环为基本结构单元,通过层间的范德华力以及层内的C—N共价键结合,构成类石墨的二维层状结构,具有性质稳定、能带结构独特、生物兼容性好、环保无毒、易于功能化、原料价廉、制备过程简单等优点。自2012年g-C_(3)N_(4)首次被发现具备ECL的性能,至今已被广泛应用到ECL中。本文根据ECL的发光机理、传感器的作用效果、传感的信号类型以及不同的检测对象进行了分类,综述了近年来g-C_(3)N_(4)在ECL传感器构建中的研究进展,并阐述了g-C_(3)N_(4)在ECL发展中存在的挑战和前景。Electrochemiluminescence(ECL)combines the characteristics of electrochemistry and chemiluminescence.Because of its high sensitivity,wide linear range and low background interference,electrochemiluminescence has attracted the attention of many researchers in analytical science.Although the traditional luminescent materials of ECL have high luminous efficiency,they still have some disadvantages,such as high price,lower sample load,etc.g-C_(3)N_(4)is a kind of metal-free semiconductor nanomaterial,which is based on triazine ring or heptazine ring as the basic structural unit.g-C_(3)N_(4)is a two-dimensional graphite-like layered structure bonded by vander Waals forces between layers and C—N covalent bonds within layers.Since g-C_(3)N_(4)was first discovered to have ECL performance in 2012,it had been widely used in the development and fabrication of ECL sensors,due to its advantages,such as stable property,unique band structure,good biocompatibility,better environmental performance,easy to function,inexpensive ingredients and simple preparation process.The research progresses of g-C_(3)N_(4)in ECL sensor construction in recent years were reviewed,according to the mechanism of ECL luminescence,the effect of sensor,the signal type of sensor,and the different types of detection objects.And the challenges and prospects of g-C_(3)N_(4)in ECL development were described as well.
