Synthesis and Photophysical Properties of Pyrene-Based Multiply Conjugated Shaped Light-Emitting Architectures: Toward Efficient Organic-Light-Emitting Diodes

Abstract

A review on the synthesis and photophys. properties of pyrene-based, multiply conjugated shaped, fluorescent light-emitting materials that have been disclosed in recent literatures, in which several pyrenes have been successfully used as efficient hole-/electron-transporting materials or host emitters or emitters in OLEDs. In this system, a series of pyrene-based, cruciform-shaped π-conjugated blue-light-emitting architectures can be prepared with an emphasis on how synthetic design can contribute to the meeting of promising potential in OLEDs applications.
