Solution processable truxene based blue emitters: Synthesis, characterization and electroluminescence studies

Truxene (10,15-dihydro-5H-diindeno[1,2-a;1?,2?-c]fluorene) derived blue emitting materials were designed and developed utilizing Suzuki and Buchwald-Hartwig type cross-coupling reactions. The target molecules T1, T2 and T3 bearing N-carbazolyl, 1-pyrenyl and N-phenyl-N-(pyren-1-yl) substituents, respectively at 2,7,12- positions, were synthesized under mild conditions by palladium-catalyzed reactions in good yields. To improve the solution processability of the material, n-hexyl chains were used as substituents at 5,5?-, 10,10?-, 15,15?- positions. From UV?vis measurements, the absorption maxima were found to be at 330 nm for T1, 356 nm for T2 and 412 nm for T3. The materials were found to be blue emitting with their emission maxima at 385 nm, 425 nm and 490 nm for T1, T2 and T3, respectively. The excited state lifetimes were investigated using time correlated single photon counting and were found to be 10 ns, 1.4 ns and 5.4 ns for T1, T2 and T3, respectively. The highest photoluminescence quantum yield was observed in the case of T2 corresponding to a value of 0.97. The compounds T2 and T3 were used as active materials for the fabrication of solution processed, single layer blue light emitting diodes, with low turn-on voltage (2?3.3 V) and Commission Internationale de l’eclairage (CIE) coordinates corresponding to (0.16, 0.23) and (0.17, 0.36) for T2 and T3, respectively.
