ring was reported. The luminescence properties of the 1/1 Eu(III) and Tb(III) corresponding complexes were investigated in air-equilibrated water and deuterated water (Tris buffer, pH 7.4) at 298 and 77 K. High luminescence lifetime (τ = 2.30 ms), quantum yield (Φ = 45%) and efficiency for the sensitized emission (ηsens = 60%) were observed for the terbium complex. A detailed study of the steps originating
一个新的配位体的基于一个DO3A部分(DO3A = 1,4,7,10-四氮杂环十二烷-1,4,7-三乙酸),作为镧系元素离子和所附发色单元托管剂合成Ñ,Ç -据报道在吡唑环的3位上被羧酸官能化的吡唑基吡啶核。在空气平衡的水和氘化水(Tris缓冲液,pH 7.4)中于298和77 K下研究了1/1 Eu(III)和Tb(III)相应配合物的发光特性。高发光寿命(τ = 2.30 ms ),量子产率(Φ = 45%)和用于发射致敏效率(η SENS = 60%)的complex络合物。报告了对从生色团单元吸收光并导致镧系元素中心发射的步骤的详细研究。
