A new bis(diphenylphosphate)diimine ligand (BP1) was prepared and evaluated for its ability for selective detection of deoxycytidine 5′-monophosphate (dCMP). BP1 exhibited off-type fluorescence in the presence of dCMP. The fluorescence of BP1 was significantly quenched upon the addition of 2.5 × 10−4 M dCMP and the detection limit was 1.25 × 10−5 M in MeCN-H2O (1:1, v/v). The binding ratio between

CMP 存在下表现出离型荧光。BP1 的荧光在加入 2.5 × 10 -4 M d
CMP后显着淬灭,检测限为 1.25 × 10 -5 M 在 MeCN-H 2 O (1:1, v/v ) 中。BP1和d
CMP之间的结合比被确定为1:1,结合常数为3.98 ± 0.60 × 10 -3 M -1。
