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.

Near UV-vis LED-excitable two-branched sensitizers for cationic, radical, and thiol-ene photopolymerizations

Two novel branched sensitizers bearing biphenyl or fluorenyl groups as the linking skeleton and triphenylamine-stilbene-thiomethyl benzonitrile as peripheral branches were designed. Strong absorption of light in the UV-vis range (λmax = 389-397 nm, εmax = 60,200-90,300 M-1 cm-1) matched the emission of new light sources, i.e., UV-vis light-emitting diodes at 365-450 nm. The reactive species produced from the photoinitiating systems based on these chromophores themselves or combined with an iodonium salt, N-vinylcarbazole, or an amine were highly efficient for versatile photopolymerizations (radical, cationic, and thiol-ene polymerizations) upon soft exposure conditions (365-450 nm light-emitting diodes). The UV-vis spectra, theoretical calculation of molecular orbitals, electrochemistry, and fluorescence quenching measurements were studied to reveal the photochemical mechanism.
