A heterotrinuclear lanthanide complex has been prepared which contains two terbium ions in DO3A-derived binding sites and a single ytterbium ion in a DTPA-like site. The luminescence properties of the system have been investigated, showing that the terbium remains in a seven-coordinate binding site throughout the synthesis, while the ytterbium occupies the eight-coordinate site. Pumping the 488 nm absorption band of the terbium ion results in energy transfer to ytterbium with emission at 980 nm.
已制备出一种异三核镧系元素配合物，其在源自DO3A的结合位点中含有两个铽离子，在类DTPA位点中含有单个镱离子。对该体系的发光性质进行了研究，结果表明在整个合成过程中铽保留在七配位结合位点，而镱占据八配位位点。泵浦铽离子的488 nm吸收带会导致能量转移至镱，并在980 nm处发射。
