    in situ from t-BuOCl and NaI. A variety of 2,5-disubstituted 1,3,4-oxadiazoles were synthesized in high yields within short reaction time. The method is also suitable for cyclization of N-acylhydrazones derived from heterocyclic aldehydes and aliphatic aldehydes. Mild reaction conditions and simple workup operations make the procedure a good alternative for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles

  • Synthesis and Properties of Polymers Containing Charge Transport Pendant Group
    作者:Hui Wang、Jeong-Tak Ryu、Young Hwan Shin、Younghwan Kwon
    DOI:10.1080/15421400903240464
    日期:2009.11.11
    Non-conjugated polymers containing charge transporting pendant groups were synthesized and characterized. Poly(N-(4-vinylphenyl)-carbazole) (PPCZ) with a hole transporting carbazole group and poly(2-methylphenyl-5-(4-vinylphenyl)-1,3,4-oxadiazole) (PPOXD) with an electron transporting 1,3,4-oxadiazole group were synthesized by free radical polymerization of corresponding monomers, respectively, N-(4-vinylphenyl)-carbazole (VPCZ) and 2-methylphenyl-5-(4-vinylphenyl)-1,3,4-oxadiazole (VPOXD). Poly(vinyl carbazole) (PVK), well-known hole transporting material, was also prepared for comparison. These polymers with moderate molecular weight and molecular weight distribution were found to be all solution-processable. Thermal, optical and electrochemical properties of these polymers were investigated for an attempt to apply for charge transporting layer and/or host matrix in emitting layer in OLEDs. It appeared that photophysical properties such as ionization potential and electron affinity were dependent on respective pendant groups in polymers. High band gap energy levels (3.19 eV similar to 3.44 eV) could make polymers a promising candidate for host matrix in OLEDs.
  • Design and synthesis of novel anthracene derivatives as n-type emitters for electroluminescent devices: a combined experimental and DFT study
    作者:G. Mallesham、S. Balaiah、M. Ananth Reddy、B. Sridhar、Punita Singh、Ritu Srivastava、K. Bhanuprakash、V. Jayathirtha Rao

    Six novel anthracene-oxadiazole derivatives, 4a (2-(4-(anthracen-9-yl)phenyl)-5- p-tolyl-1,3,4-oxadiazole), 4b (2-(4-(anthracen-9-yl)phenyl)-5-(4- tert-butylphenyl)-1,3,4-oxadiazole), 4c (2-(4-(anthracen-9-yl)phenyl)-5-(4-methoxyphenyl)-1,3,4-oxadiazole), 8a (2-(4-(anthracen-9-yl)phenyl)-5- m-tolyl-1,3,4-oxadiazole), 8b (2-(3-(anthracen-9-yl)phenyl)-5-(4- tert-butylphenyl)-1,3,4-oxadiazole) and 8c (2-(3-(anthracen-9-yl)phenyl)-5-(3,4,5-trimethoxyphenyl)-1,3,4-oxadiazole) have been synthesized and characterized for use as emitters in organic light emitting devices (OLEDs). They show good thermal stability (Td, 297–364 °C) and glass transition temperatures (Tg) in the range of 82–98 °C, as seen from the thermo gravimetric analysis and differential scanning calorimetric studies. The solvatochromism phenomenon and electrochemical properties have been studied in detail using UV-Vis absorption, fluorescence spectroscopy and cyclic voltammetry. TD-DFT calculations have been carried out to understand the electrochemical and photophysical properties. The spatial structures of 4b and 8c are further confirmed by X-ray diffraction analysis. Un-optimized non-doped electroluminescent devices were fabricated using these anthracene derivatives as emitters with the following device configuration: ITO (120 nm)/α-NPD (30 nm)/ 4a–4c or 8a–8c (35 nm)/BCP (6 nm)/Alq3 (28 nm)/LiF (1 nm)/Al (150 nm). Among all the six compounds, 8a displays the maximum brightness of 1728 cd m−2 and current efficiency 0.89 cd A−1. Furthermore, as an electron transporter, 8a exhibited superior performance (current efficiency is 11.7 cd A−1) than the device using standard Alq3 (current efficiency is 8.69 cd A−1), demonstrating its high potential for employment in OLEDs. These results indicate that the new anthracene-oxadiazole derivatives could play an important role in the development of OLEDs.
