Li, Bijin published the artcileUnexpected Sole Enol-Form Emission of 2-(2′-Hydroxyphenyl)oxazoles for Highly Efficient Deep-Blue-Emitting Organic Electroluminescent Devices, Product Details of C9H6BrNO, the publication is Advanced Functional Materials (2017), 27(9), n/a, database is CAplus.
Considerable efforts have been devoted to the development of highly efficient blue light-emitting materials. However, deep-blue fluorescence materials that can satisfy the Commission Internationale de l’Eclairage (CIE) coordinates of (0.14, 0.08) of the National Television System Committee (NTSC) standard blue and, moreover, possess a high external quantum efficiency (EQE) over 5%, remain scarce. Here, the unusual luminescence properties of triphenylamine-bearing 2-(2′-hydroxyphenyl)oxazoles (3a-3c) and their applications in organic light-emitting diodes (OLEDs) are reported as highly efficient deep-blue emitters. The 3a-based device exhibits a high spectral stability and an excellent color purity with a narrow full-width at half-maximum of 53 nm and the CIE coordinates of (0.15, 0.08), which is very close to the NTSC standard blue. The exciton use of the device closes to 100%, exceeding the theor. limit of 25% in conventional fluorescent OLEDs. Exptl. data and theor. calculations demonstrate that 3a possesses a highly hybridized local and charge-transfer excited state character. In OLEDs, 3a exhibits a maximum luminance of 9054 cd m-2 and an EQE up to 7.1%, which is the first example of highly efficient blue OLEDs based on the sole enol-form emission of 2-(2′-hydroxyphenyl)azoles.
