摘要：

A series of conjugated hyperbranched molecules with 1,3,5-triphenylbenzene rings as cores and with different connecting groups have been synthesized. Their structures were characterized by FTIR,1H-NMR and13C-NMR. These molecules exhibit good solubility and film-forming ability. In particular, they have high thermal stabilityTID> 350 °C. The spectroscopic properties of these molecules were studied both in solution and as spin-coated films. The twisted intramolecular charge transfer TICT state was observed in hyperbranched molecules containing triphenylamine as the connecting unit. Light emitting devices ITOPEDOThyperbranched moleculeBaAl have been fabricated.
