The formation of excimers in DBQA and DMQA and their better performance in FETs seem to be a bit of a handwaving argument. Since there are no structural properties shown, it is not clear whether this argument is correct. I’m not suggesting that the authors do a complete XRD analysis, but my suggestion is that the authors provide a more balanced view and should caution readers. It is conceivable that with other FET architectures, DPQA show improved FET characteristics.
You raise a valid concern about the lack of structural evidence to support the argument that excimers form in DBQA and DMQA, and that these excimers lead to improved FET characteristics. It is important for authors to provide a balanced view of their findings and to be transparent about any limitations or uncertainties in their research.
It would be beneficial for the authors to provide additional supporting data, such as optical or spectroscopic measurements, to help demonstrate the formation of excimers in DBQA and DMQA. Additionally, the authors should also consider examining the performance of DPQA in other FET architectures to see if the improved FET characteristics are specific to a particular device structure or if they are a general feature of DPQA.
Additionally, it would also be valuable for the authors to provide a more in-depth explanation of the underlying mechanisms that lead to the improved FET characteristics, as this could help to further support their argument and provide a more comprehensive understanding of their findings.
Overall, it's important for authors to be transparent and honest about their research. It's also important for readers to critically evaluate the research and draw their own conclusions.
