Abstract

In this paper, time-resolved PL, lifetime and crystallization of a novel organic, 2,8-di(t-butyl)-5,11-di[4(t-butyl)phenyl]-6,12-dipehnylnaphthacene, which is considered to be potential candidate to substitute the conventionally used 5,6,11, 12-tetraphenylnaphthacene for a higher efficient yellow-color organic LED. were investigated. The PL intensity will reduce when the irradiation time increases because of photo-quenching. It is shown that oxidation is the dominant reason for photo-quenching. In addition, TBRb has two lifetimes. The short one is ∼5ns and the long one is ∼31ns. They are considerably contributed by the short PL peak and long PL peak respectively. Furthermore, we first report, to the best knowledge, crystallization of TBRb at low temperature of 11K and with irradiation.
