| We have prepared and characterized a series of 9,10-bis(triisopropylsilylethynyl)anthracene derivatives for use in light emitting diodes (OLEDs). The derivatives were prepared in an attempt to change the solid-state packing of the anthracene units, in particular the amount of p-interaction taking place between each unit. I will discuss how the altering of the solid-state order of the anthracenes drastically affected the properties of the OLEDs prepared from them. We are currently preparing new derivatives to optimize the p-interaction of the anthracenes to make OLEDs with brighter emission, lower turn-on voltages, and higher efficiencies. Further substitution of the anthracenes is also taking place to fine tune the emission of the OLEDs. Another aspect of the OLEDs we are currently exploring is the morphology of the thin films formed by chemical vapor deposition for the OLEDs. The morphology of the films will show whether the properties of the OLEDs are due to the crystalline packing we have seen for the anthrcene derivatives. |
