Abstract

1,8-naphthalimide (NI) derivatives are custom-modified specifically as emitting layers in organic light-emitting devices (OLEDs) to realize full-color emission and improve the lifetime and luminous stability. In this work, a multifunctional cruciate-type blue emitter BCz-NI based on N-buthyl-1,8-naphthalimide linked with the N,N′-bicarbazole donor group was designed and synthesized with D-A structured. The emitter BCz-NI shows hybridized local and charge-transfer state characteristics to make full use of the formed excitons and reduce losing energy, which is attributed to the cruciate-type core providing efficient steric hindrance to promotes energy transfer. The non-doped OLEDs based on BCz-NI as a blue light material to achieve warm white light emission with commission internationale de leclairage coordinates of (0.41, 0.37) by combining the blue light material and the exciplex generated with the electron transport layer. This research would provide theoretical basis for complementary white light OLED by forming exciplex.

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
