Resumen
Abstract In this study, we report on the syntheses of novel angular fused azaacenes. For this purpose, the synthesis of the bis-diamine 2 (TABEF) could be shortened and optimized. The condensation reaction of 2 with different types of 1,2-diketones yielded new azaacene derivatives of types 10, 11 and 12. Analogously, 2 was cyclized with thionyl chloride to give the piazthiol derivative 13. The optical and electrochemical properties of all new compounds were investigated by UV/Vis absorption, fluorescence emission spectroscopy and cyclovoltammetric measurements.

Resumen
Polyacenes and polyazaacenes have attracted significant attention because of their potential applications in material science, particularly their expected magnetic properties, which make them promising for device applications. However, synthesizing polyacenes/azaacenes is challenging due to their low solubility and stability. To address these issues, we utilize “thermal and photochemical precursor methods”. Briefly, bicyclo[2.2.2]octadiene(BCOD)-fused acenes can be converted to the corresponding acenes by the thermally induced retro-Diels-Alder reaction, while alpha-diketone-type precursors ca

Resumen
Partial substitution of CH groups in the skeletons of linearly fused phenyl rings provides an appreciable possibility to tailor their properties. Among them, azaacenes induced from a partial substitution of oligoacenes by nitrogen are one of the most promising derivatives with a view of their potential application in organic electronic devices as a novel organic n-type semiconductor. Hence this review focuses on recent progress in the synthesis of azaacenes and their applications beyond organic field-effect transistors (OFETs) such as organic light-emitting diodes (OLEDs), phototransistors, ph

Tuning the substituents allows modulating emission wavelengths across the visible spectrum. Substitution with 3-methoxy-2-methylthiophene exhibits a quantum yield of 35%.
