    Directed lithiation of a pyrene-1-carboxamide as a route to new pyrenyl fluorophores
    摘要:
    The lithiation of N-tert-butylpyrene-1-carboxamide with nBuLi-TMEDA in THF at -78 degrees C afforded, after quenching with chlorosilanes, the corresponding 2-(trialkylsilyl)pyrene-1-carboxamides. When DMF and diethyl oxalate were used as quenchers compounds having 8-tert-butyl-7-hydroxy-8,9-dihydro-7H-phenaleno-[1,9-ef]isoindole skeleton were obtained. The oxidation of compound having secondary OH group with Jones' reagent afforded 8-tert-butyl-7-hydroxy-8,9-dihydro-7H-phenaleno-[1,9-ef]isoindole-7,9(8H)dione. All of the synthesized compounds displayed fluorescence in solution (lambda(max) = 425-451 nm; Phi(F) = 15.1-40.8%) and in the solid state ((lambda(max) = 410-555 nm; Phi(F) = 6-40%). The silylated amides display in the solid state monomer emission whereas in the case of the of phenalenoisoindole derivatives the emitting species are pi-stacked aggregates. The formation of aggregates in the crystals of the latter compounds was confirmed by a single-crystal X-ray diffraction study. (c) 2015 Elsevier Ltd. All rights reserved.

    具有羰基基团的多环芳烃发光过程的其他见解:萘,蒽和P的仲N-烷基和叔N,N-二烷基羧酰胺的光物理性质
    摘要:
    在这里,我们报道了N-烷基和N,N-二烷基羧酰胺基团对多环芳烃发色团的荧光性质的取代作用,从而控制了它们的荧光性质。使用具有不同极性的溶剂获得的化合物的荧光性质几乎没有变化,表明改性的化合物没有形成电荷转移态。在低温(78 K)和粘性溶剂中进行的TD-DFT计算和测量表明,N-烷基和N,N-二烷基羧酰胺基团倾向于减少来自系统间交叉的贡献并增加来自内部转化的贡献。考虑到醛和酮等低荧光羰基化合物的荧光机理是通过体系间交叉控制的,而羧酸和酯等高发光羰基化合物的荧光机理是通过辐射过程控制的,可以说是光物理过程。的ñ -烷基和ñ,ñ二烷基甲酰胺是新颖的。另外,对于激发态的计算结果表明,除了溶剂粘度和温度以外,还可以通过选择合适的多环芳族烃或酰胺结构来控制这种作用。
