          摘要:

          通過吲哚衍生物與1,8-萘內酰亞胺縮合及氟硼化反應,得到meso位無取代和甲基取代的兩種配體(Ⅰ、Ⅲ)及兩種N,N-氟硼配合物(BODIPY)染料(Ⅱ、Ⅳ)。其結構和光學性能經核磁、高分辨質譜、單晶、紫外可見吸收光譜、熒光發射光譜和固體熒光光譜進行了表征。結果表明,meso位引入甲基后配體Ⅲ較配體Ⅰ的固體熒光發射峰紅移了34 nm。BODIPY染料具有較強的雙效熒光(液體和固體熒光),其中BODIPYⅣ的液固熒光量子產率分別高達66.0%和76.3%,其固體熒光量子產率較meso位無取代Ⅱ(14.6%)提高了4.2倍。Ⅳ較強的雙效發光可歸因于其固體堆積方式中無C—H…π作用以及層與層之間的“頭-尾”π-π堆積。不同于其他提高固態熒光的策略,在母體meso位引入小位阻甲基的策略使BODIPY具有雙效紅光發射性能,亦豐富了雙效有機發光材料的種類。

          Abstract:

          Meso-unsubstituted and methyl group substituted BODIPYs and their ligands have been obtained with indole derivatives and 1, 8-naphthalenimide by condensation and coordination reactions. Structures were characterized by NMR, HRMS, single crystal and electronic spectra. The results indicated that the solid emission spectra red-shifted 34 nm by the introduction of methyl group at meso-position. BODIPYs show high intensity fluorescence in dual state (solution and solid state). The liquid and solid fluorescence quantum yields of Ⅳ are as high as 66% and 76.3% respectively. Its solid fluorescence quantum yield is 4.2 times higher than that of Ⅱ (14.6%). The excellent optical properties of Ⅳ can be attributed to the absence of C—H…π interaction and different “head to tail” π-π stacking between layers. Excellent dual state emission luminogens glowing at red region have been obtained by the introduction of methyl group, which is different from other strategies and enriches the types of dual state organic luminescent materials.
