Usage

Uses

Used in Organic Light-Emitting Diodes (OLEDs):
TPD is utilized as a hole-transporting layer in OLEDs for its ability to facilitate the movement of holes, which are essential for the device's light-emitting properties. Its high hole mobility and good film-forming properties contribute to the enhanced performance and efficiency of OLEDs.
Used in Organic Solar Cells:
In the field of organic solar cells, TPD is employed as a hole-transporting material to improve the charge separation and collection processes. Its stability and electrical properties play a significant role in boosting the overall efficiency and durability of these solar energy conversion devices.
Used in Other Organic Electronic Devices:
Beyond OLEDs and organic solar cells, TPD's versatility extends to other organic electronic applications where its thermal and electrical properties are advantageous. Its use as a hole-transporting material can be found across various devices that require efficient charge transport mechanisms for optimal performance.

Three color random fluorene-based oligomers for fast micrometer-scale photopatterning

In this contribution we show that random fluorene cooligomers with photo reactive acrylate units can be prepared in a simple 1-step Yamamoto synthesis. The acrylate functionalities are preserved quantitatively under Yamamoto conditions.NMRand Maldi-ToF measurements point to an almost statistical incorporation of the comonomers into the oligomer chain. Maldi-ToF analyses give a further insight into the chain compositions, and we found fluorene-only oligomers to be present in low quantities. Thin films of the aromatic amine containing cooligomer show a blue fluorescence, the benzothiadiazole oligomer shows yellow photoluminescence, and the bithiophene oligomer emits orange-red light upon excitation. Compared to pure fluorene oligomers with a HOMO of 5.7 eV the HOMOlevels of the TPD and bithiophene derivatives are increased to 5.25 and 5.31 eV, respectively, whereas theHOMO level of the benzothiadiazole oligomer is decrased to 5.85 eV. Photolithography experiments reveal that a careful optimization of the conditions, for example, the choice of the photoinitiator, temperature, and irradiation wavelength, leads to well-resolved micrometer sized patterns. A minimum feature size of 1 μm was obtained. Thus we showed that with a simple 1-step Yamamoto coupling oligomers with photo-cross-linkable acrylate groups are accessible. UV irradiation leads to densely cross-linked, insoluble networks. Thus these materials are ideal candidates for multilayer as well as patterned semiconducting devices.
