Oxadiazole-Triphenylamine derivatives for OLEDs

SPIE Proceedings, 2005
Electroluminescent bipolar small molecules have been attracted with great interests recently. They are found to exhibit many interesting features such as (i) reducing the structural complexity of organic light emitting diodes (OLEDs) from multilayer heterojunction to monolayer homojunction devices; (ii) offering molecular p/n junction, and (iii ...

1,3,4-Oxadiazole Bridges: A Strategy to Improve Energetics at the Molecular Level.

Angewandte Chemie, 2020
Many energetic materials synthesized to date have limited applications because of low thermal and/or mechanical stability. This limitation can be overcome by introducing structural modifications such as a bridging group.

Infrared spectra of 1,3,4-oxadiazole and 2,5,-dimethyl-1,3,4-oxadiazole. Vibrational assignment of 1,3,4-oxadiazole

Journal of Molecular Spectroscopy, 1967
Abstract The infrared absorption spectrum of 1,3,4-oxadiazole has been recorded in the region 5000-400 cm −1 in the vapor and in the liquid phases, in CS 2 and C 2 Cl 4 solutions. Also, the infrared absorption spectrum of liquid 2,5-dimethyl-1,3,4-oxadiazole was recorded in the same region. A tentative assignment of the fundamental vibrations of 1,

Poly‐1,3,4‐oxadiazoles. I. Polyphenylene‐1,3,4‐oxadiazoles

Journal of Polymer Science Part A: General Papers, 1965
AbstractPolyphenylene‐1,3,4‐oxadiazoles have been prepared from benzenedicarboxylic acids or their derivatives and hydrazine by solution polycondensation in fuming sulfuric acid or polyphosphoric acid. These polymers were characterized by good thermal stability, and the molecular weights attained were high enough for the products to exhibit fiber‐or ...

Oxadiazole grafts in peptide macrocycles

Nature Chemistry, 2016
Synthetic methods that provide control over macrocycle conformation and, at the same time, mitigate the polarity of peptide bonds represent valuable tools for the discovery of new bioactive molecules. Here, we report a macrocyclization reaction between a linear peptide, an aldehyde and (N-isocyanimino)triphenylphosphorane.
