A platinum(II) bipyridyl complex bearing bis‐ureidopyrimidinone (Pt‐bisUPy) has been designed and its self‐assembling behavior has been thoroughly investigated by 1H NMR, DOSY NMR, Ubbelohde viscometry analysis, UV/Vis, and emission spectroscopies. Pt‐bisUPy underwent concentration‐dependent ring‐chain polymerization in apolar solvents. Hydrogen‐bonding interactions play an important role during the
设计了带有双脲基嘧啶酮的铂(II)联吡啶基络合物(Pt-bisUPy),并对其自组装行为进行了彻底的研究[ 1]。1 H NMR,DOSY NMR,Ubbelohde粘度分析,UV / Vis和发射光谱。Pt-bisUPy在非极性溶剂中经历了浓度依赖性的环链聚合反应。氢键相互作用在超分子聚合物的形成过程中起着重要作用。通过细乳液法,将氢键结合的超分子聚合物在水中转化为纳米颗粒。这些纳米粒子表现出很强的π–π准分子发射。Pt-Pt相互作用产生的金属-金属-配体电荷转移(MMLCT)在发射光谱中不显着。即使在有氧条件下,纳米颗粒的磷光仍然持续。这些磷光纳米材料的三重态是长寿命的,并具有中等的发射量子产率。此外,
