The synthesis, structure, and properties of six luminescent pyridylpyrrolide complexes and the first structural characterization of pyridylpyrrolide metal complexes are reported. A series of new zinc complexes, bis(pyridylpyrrolyl)zinc, (R2PyrPy)2Zn (R = Me, Et, iPr, tBu, and Ph), that vary in their substituents on the pyrrole ring (Me, Et, iPr, tBu, and Ph), were prepared. Pyrrole substitution produced
报道了六个发光的吡啶基吡咯化物配合物的合成,结构和性质,以及吡啶基吡咯化物金属配合物的首次结构表征。一系列新的锌络合物,双(吡啶基吡咯基)锌,(R 2 PyrPy)2 Zn(R = Me,Et,i Pr,t Bu,and Ph)在吡咯环上的取代基(Me,Et,i Pr,t Bu,and Ph)分别是准备好了。吡咯取代在配合物中产生小的结构变化,并且几乎不影响荧光性质。发现锌配合物是发光的,在495nm处发射(Φ 分别为0.32、0.32、0.31、0.19和0.57)。制备了硼类似物(Me 2 PyrPy)BF 2,发现它与锌络合物具有共同的发光特性,它们在505 nm(Φ = 0.22)处发射,但不发光。水-灵敏度。总共报告了四个晶体结构,t Bu 2 PyrPyH,(Me 2 PyrPy)2 Zn,(t Bu 2 PyrPy)2 Zn和(Me 2 PyrPy)BF 2。t Bu 2 P
