A series of new palladium complexes containing a Cu(I) photosensitizing unit were synthesized in good yields by the reaction of [(bpm)Pd(CH₃)(solv.)]⁺ (bpm = 2,2′-bipyrimidine) complex with Cu(I) precursors. One of the Cu–Pd dinuclear complexes was structurally characterized by single-crystal X-ray diffraction and showed sterically congested Cu center. The Cu–Pd complexes catalyzed styrene polymerization under visible-light irradiation to furnish polystyrenes via a nonradical mechanism.

具有地球上丰富的铜光敏剂的铜钯双核配合物：合成和光聚合

通过[（bpm）Pd（CH ₃）（solv。）] ⁺（bpm = 2,2'-bipyrimidine）络合物与[（bpm）Pd（CH ₃）（solv。）] ⁺（bpm = 2,2'-bipyrimidine）络合物的反应可以高收率合成一系列含有Cu（I）光敏单元的新型钯络合物Cu（I）前体。一种Cu-Pd双核络合物的结构由单晶X射线衍射表征，并显示出Cu中心的空间拥挤。Cu-Pd络合物在可见光照射下催化苯乙烯聚合，从而通过非自由基机理提供聚苯乙烯。
