reactive probe, 1-(benzo[d]thiazol-2-yl)naphthalen-2-yl-picolinate (BTNP), was designed and synthesized. BTNP acts as a highly selective probe to Cu(2+) in DMSO/H2O (7/3, v/v, Tris-HCl 10mM, pH=7.4) solution based on Cu(2+) catalyzed hydrolysis of the picolinate ester moiety in BTNP, which leads to the formation of an ESIPT active product with dual wavelength emission enhancement. The probe also possesses
设计并合成了一种新型的反应性探针1-(苯并[d]噻唑-2-基)萘-2-基-吡啶甲酸(BTNP)。BTNP作为基于Cu(2+)催化的吡啶甲酸酯部分水解的DMSO / H2O(7/3,v / v,Tris-HCl 10mM,pH = 7.4)解决方案中Cu(2+)的高选择性探针在BTNP中,这导致形成具有双波长发射增强作用的ESIPT活性产物。该探针还具有合成简单,反应迅速和灵敏度高的优点。拟一级反应速率常数经计算为0.205min(-1)。此外,还探讨了BTNP在活细胞和真实水样中Cu(2+)检测中的应用。
