四膦配体dpppda与AgNO 3反应生成了两种一维配位聚合物，分别含有立方体和椅状[Ag 4（NO3）4]簇。由DFT计算支持的ESR光谱表明存在dppstecpda+，这是一种通过分子内配体-金属电荷转移（LMCT）形成的Wurster蓝色样自由基阳离子。这种LMCT导致更高的AgI → Ag 0电位和良好的光电流响应。
Tetraphosphine ligand dpppda reacts with AgNO3 to generate two 1D coordination polymers containing cubic and chair-like [Ag4(NO3)4] clusters. ESR spectroscopy supported by DFT calculations indicated the presence of dpppda˙+, a Wurster's blue – like radical cation formed by intramolecular ligand-to-metal charge transfer (LMCT). This LMCT results in higher AgI → Ag0 potentials and good photocurrent responses.
