Reviewer 1 Report
In this contribution, Podda, Aragoni and coworkers designed 2,7-bis(pyridin-3-ylethynyl)fluoren-9-one obtained by a double Sonogashira corss coupling reaction from 2,7-dibromofluoren-9-one. The basil photophysical properties of title compound were briefly decribed. I think that this manuscript fits the standard of Molbank and I therefore recommend the publication of this short note.
A list of point to be adressed before publication are listed below:
1- Scheme 1: This is a figure not a scheme. Please add correspondin litterature reference linked to each structure.
2- Scheme 2: please add synthetic yield.
3- Figure 1: Wavelength instead of wavelenght (2 times)
4- I would suggest if possible to measure photoluminescence quantum yield (at least in solution).
5- I strongly suggest to deposit the x-ray structure to CCDC and provided the corresponding CCDC number in the manuscript.
6- Please select and attribut the main IR bands.
Author Response
Dear Reviewer,
Thank you for your comments and recommendations.
We changed the manuscript according to the suggested points as detailed in the followings:
1- Scheme 1: This is a figure not a scheme. Please add corresponding literature reference linked to each structure.
Scheme 1 has been renamed as Figure 1. Associated references are indicated in square brackets in the caption.
2- Scheme 2: please add synthetic yield.
Scheme 2 has been renamed as Scheme 1 and the reaction yield included.
3- Figure 1: Wavelength instead of wavelenght (2 times)
Figure 1 has been renamed as Figure 2 and the typing errors corrected.
4- I would suggest if possible, to measure photoluminescence quantum yield (at least in solution).
The photoluminescence quantum yield was determined in chloroform and is included in the amended version of the manuscript.
5- I strongly suggest to deposit the x-ray structure to CCDC and provided the corresponding CCDC number in the manuscript.
The crystal structure was deposited in the CCDC as stated in the following section of the manuscript: Data Availability Statement: Crystallographic data were deposited at CCCD (CIF deposition number 2225299).
6- Please select and attribute the main IR bands.
The main IR bands of the title compounds were attributed and reported in the manuscript: “FTIR analysis showed the stretching modes of alkynyl and carbonyl moieties at 2206 and 1716 cm−1”.
The manuscript has been revised according to the reviewer suggestions and the changes evidenced.
