lifetime of ∼5 ns in acetonitrile. It shows selective sensing of hydrogen pyrophosphate (HP2O73–) through 20-fold enhanced emission intensity (ϕf = 0.039) with a 15 nm red shift in emission maxima even in the presence of a large excess of various competitive anions like F–, Cl–, AcO–, BzO–, NO3–, HCO3–, HSO4–, HO–, and H2PO4– in acetonitrile. Selective change in the decay profile as well as in the lifetime
基于缺铜的氰尿酸平台铜催化的叠氮化物-炔烃环加成反应,合成了一种新的双杂三核Ru(II)络合物(1 [PF 6 ] 6),即CuAAC点击生成的配体1,3,5-三[[(2-氨基乙基-1H-1,2,3-三唑-4-基)-吡啶] -1,3,5-三嗪烷-2,4,6-三酮(L1)。配合物1 [PF 6 ] 6在室温下显示弱发光(ϕ f = 0.002),在乙腈中的寿命短至约5 ns。它显示了焦磷酸氢的选择性传感(HP 2 ö 7 3-)通过20倍增强的发光强度(φ ˚F= 0.039),在发射最大值,即使在大量过量的,如F的各种竞争性阴离子的存在下,15纳米红移- ,氯-,ACO -,BZO -,NO 3 -,HCO 3 -,HSO 4 -,HO –和H 2 PO 4 –在乙腈中。在存在HP 2 O 7 3–(108 ns)的情况下,衰减曲线的选择性变化以及1 [PF 6 ] 6的寿命进一步支持了其对HP
