Dendrimers for organic light-emitting diodes

Carbazole-based polymers as hosts for solution-processed organic light-emitting diodes: Simplicity, efficacy

“…Dendrimers are another kind of materials that can be incorporated in polymers [180,181]. As main interest, dendritic side chains can efficiently suppress the formation of aggregates/excimers by their shielding effects [182,183].…”

Thermally Activated Delayed Fluorescence Emitters for Deep Blue Organic Light Emitting Diodes: A Review of Recent Advances

“…Since a decade, boron-based materials have been the focus of numerous researches, especially devoted to Organic Electronics as these materials exhibit a remarkable electron mobility due to the vacant p-orbital of the boron atom [74][75][76]89,90]. Triarylboron derivatives are also characterized by their bulkiness and these materials are also strong electron withdrawing groups.…”

“…To overcome this issue, Li et al proposed to use sulfone based dendrimers (6-7, Figure 2) [72]. Dendrimers exhibit great advantages owning to their well-defined molecular structure, precisely controllable molecular size, as well as the inhabited molecular interactions [73,74]. However, until now, the reported blue TADF dendrimers are still rare [75], while TADF dendrimers displaying green and greenish-blue emissions have been utilized for the fabrication of non-doped solution-processed OLEDs while exhibiting satisfying electroluminescent performance [75][76][77][78].…”

Synthesis and properties of novel perylenebisimide-cored dendrimers

“…One typical feature of the dendrimer is that the core, dendron and surface group can be flexibly and separately functionalized to generate different functional materials [14]. For example, dendrimers with different surface groups have been shown to be promising sensing applications [15], while dendrimers with certain chromophores can serve as emitters in OLEDs and light-harvesting systems [16,17].…”
