through electrostatic interaction between two oppositely charged complexes. This probe exhibits ratiometric photoluminescence response to different oxygen concentrations with two separated emission bands. Furthermore, the application of this probe in ratiometric and lifetime imaging of oxygen content changes in living cells has been demonstrated.
                                    在这项研究中,基于软盐复合物的探针已被用于测量活细胞中氧含量的变化。
锌(II)配合物[Zn(tpy)2 ] 2+(CH 3 COO –)2 tpy = 3-[(2,2':6',2''-萜啶)-4'-yl]-选择了9-己基-9 H-
