摘　　要：文章设计并合成了一种检测硫化氢(H_(2)S)的近红外荧光探针XI-H_(2)S.探针XI-H_(2)S是由以氧杂蒽为骨架的近红外荧光团XI-OH和对H_(2)S响应的响应基团2,4-二硝基苯磺酰基组成.由于2,4-二硝基苯磺酰基有强吸电子效应,会将探针的ICT过程打断,H_(2)S可以使苯磺酰基硫解,使探针的ICT过程恢复,产生明显的近红外荧光信号,实现荧光从无到有的变化.荧光探针XI-H_(2)S具有发射波长长(716 nm)、选择性好、响应速度快、抗干扰性强和检测限低(651 nM)等优点,同时探针XI-H_(2)S可被应用于不同水样中H_(2)S的检测.A near infrared fluorescence probe XI-H_(2)S for detecting hydrogen sulfide(H_(2)S)is designed and synthesized in this paper.The probe XI-H_(2)S is composed of a near-infrared fluorophore XI-OH with oxanthracene as the skeleton and a response group of 2,4-dinitrobenzene sulfonyl in response to H_(2)S.Due to the strong electron absorption effect of 2,4-dinitrobenzene sulfonyl group,the ICT process of the probe will be interrupted.H_(2)S can thiolize benzene sulfonyl group,restore the ICT process of the probe,produce obvious nearinfrared fluorescence signal,and realize the change of fluorescence from zero to zero.Fluorescent probe XI-H_(2)S.has the advantages of long emission wavelength(716 nm),good selectivity,fast response speed,strong antiinterference,and low detection limit(651 nM),etc.At the same time,the probe XI-H_(2)S has been applied to the detection of H_(2)S in different water samples.
