The influence of interlayer with fluorene and arylamine materials on solution processed organic light emitting devices using small molecules as emissive layer (SM‐OLEDs) was studied. The SM‐OLEDs using fluorene and arylamine‐containing polymer as interlayer had low efficiency and extremely short lifetime. On the other hand, the lifetime was improved by inserting arylamine‐containing hole transport material between interlayer and emissive layer. In our experiment using several materials of small molecules, we found that the presence of fluorene unit leads to significant decrease in lifetime.
