13. In particular, even if in the blend, this problem can be limited by properly designing the molecules: a critical dependence on the deposition and external conditions is, in general, always present. All these factors make accurate control of all the deposition and materials parameters necessary, thus resulting in an increase of the production costs.

23. Moreover, we also stress that the red-shifted emission could be not due to defects and/or impurities, because all the investigated compounds have been synthesized and purified with the same procedure, but the low energy peaks are present only in compounds 1 and 2, where they are expected.
