Encapsulated cores: Host-free organic light-emitting diodes based on solution-processible electrophosphorescent dendrimers

A method to control the molecular structure of a single material using solution-processible conjugated dendrimers that demonstrate highly efficient, host-free, dendrimer light-emitting diodes (DLED), was presented. It was studied that a control over the intermolecular interactions can be engineered easily with the result showing zero necessity for the host material. It was also studied that the dendrimers are ideal nanomaterials for the development of high-performance phosphorescence materials for the use in electroluminescence applications. Formulation of host-free dendrimers-based organic light emitting diodes (OLED) is a significant step towards development of simple-to-fabricate, low-cost, high-performance organic light-emitting displays.
