在这项研究中，我们将重点放在砷作为一个新的潜在基序，用于设计高效，发光镧系配合物的配体。含Eu3+配合物的氧化三苯larsine光敏能量转移效率比含Eu3+配合物的氧化三苯膦光敏能量转移效率高7.9倍。这主要是由于砷的重原子效应，通过评价它们对应的Gd3+配合物的光致发光光谱来支持这一点。
In this study, we focused on arsenic as a new potential motif for the ligand design of high-efficiency, luminous lanthanide complexes. A Eu3+complex bearing triphenylarsine oxide had a photosensitized energy-transfer efficiency 7.9 times higher than that of a Eu3+complex bearing triphenylphosphine oxide. This is mainly due to the heavy-atom effect of arsenic, which was supported by evaluating the photoluminescence spectra of their corresponding Gd3+complexes.
