9,10-Di-(1'-naphthyl)anthracene is often used as electroluminescence materials in organic light-emitting diodes. Because of the hindered rotation about the sigma-bond between naphthyl and anthracene chromophore, two possible stereoisomers can be isolated. HPLC, H-1 NMR, and C-13 NMR spectra gave two different sets of peaks and the X-ray single crystal analysis confirmed the structures of the two isomers, anti and syn. syn was more soluble than anti in THF as well as toluene and the thermal properties of the two were quite different. Differential scanning calorimetry study and HPLC analysis showed that the isomerization between anti and syn in the solid state took place at >370 degrees C. (C) 2010 Elsevier Ltd.

A variety of polyaromatic compounds beating 1- and 2-naphthyl groups were prepared from the reactions of corresponding halides with tri(1- and 2-naphthyl)indium in good to excellent yields. Thermal, photophysical and electrochemical behaviors of carbazoles having naphthyl groups were studied. They have shown to be promising host and hole transporting materials in organic electroluminescence due to their high thermal stability, electrochemical reversibility and wide band gap.
Acenaphthoimidazolylidene‐Ligated Palladacycle Enabled Suzuki‐Miyaura Cross‐Coupling Employing Equimolar Organoboron for Tri‐Ortho‐Substituted Bi(hetero)aryls and Teraryls
AbstractThe Pd‐catalyzed Suzuki‐Miyaura cross‐couplings (SMRs) are utilized as the most practical method to construct C−C bond, especial for biaryls. However, a major disadvantage of current protocols is the requirement of excess organoboron coupling partner (1.5–3.0 equiv.). Herein, a novel palladacyclic 1,3‐bis(2,6‐diisopropylphenyl)acenaphthoimidazol‐2‐ylidene (AnIPr) precatalyst possessing a chiral oxazoline was designed, which enabled a general protocol towards bulky tri‐ortho‐substituted biaryls, ternaphthalenes and diarylanthracenes via the Pd‐catalyzed SMR employing equimolar organoborons and aryl bromides. A remarkable scope of substrates with various functional groups and heterocycles were well compatible with an adaptability to synthesize useful ligands.
