| The quinacridone chromophore has been shown to have uses in photovoltaics and as a guest emitter in OLED devices. However, extreme insolubility coupled to inefficiency problems due to aggregation has hampered its widespread use. To address this problem, we have dendritically encapsulated quinacridone with poly (benzyl-aryl ether) dendrons in order to disrupt aggregation. Chromophore insulation has resulted in non-aggregation of species in the solid state demonstrated by increased photoluminescence efficiencies as dendrimer generation increases. Furthermore, our dendrimers are now soluble in common organic solvents allowing for device fabrication by spin-casting. |
