Dendrimers for organic light-emitting diodes

Abstract

Dendrimers are now an important class of materials for use in organic light-emitting diodes (OLEDs). In this Highlight, we make a brief summary of the recent advances on OLEDs by using dendrimers as active materials. In particular, we will focus on several issues related to both the intrinsic structural features and properties, including dendrimer generation and charge mobility, the site isolation effect and prevention of energy transfer, and the host-free character. The potential applications for white electroluminescence via simple dendrimer blending, and host-free blue phosphorescent dendrimers are discussed. Finally, the strategy for dendrimer synthesis will be also discussed.
