4,4′-([1,2,5]Thiadiazolo[3,4-d]pyridazine-4,7-diyl)bis(N,N-bis(4-methoxyphenyl)aniline)
Round 1
Reviewer 1 Report
I reviewed the manuscript entitled “ 4,4’-([1,2,5]Thiadiazolo[3,4-d]pyridazine-4,7-diyl)bis(N,N’-bis(4-methoxyphenyl)aniline)” for publication in Molbank. The synthesis and various spectroscopic properties of the title compound are reported, as well as elemental analysis and a mass spectrum. The synthetic details and characterization are sufficiently detailed to confirm identity of the title compound. The supplementary info is sufficient and clear. Though the intent of this type of submission (Short Note) is intended to be brief, the authors do not compare either the synthetic details of the title compound with related compounds or the spectroscopic features with other related systems. Some minor English grammar fixes are needed as well. I suggest this manuscript be accepted pending revisions addressing the comments detailed here:
1. Abstract: last sentence, poor grammar “A luminescent properties…” fix
2. intro, line 27, replace “set-ups” with a more formal word, perhaps “applications”?
3. page 2, line 67, reword the phrase “probably due to the presence of non-radiative conversion”; do you mean non-radiative processes?
4. related to the emission, no excitation wavelength is specified; include this in the methods section
5. also related to the luminescence; no mention is made of whether the solution was deaerated or not, as the presence of oxygen might also likely be the cause of your very weak emission intensity. It may be worth collecting an emission spectrum of a deaerated solution to see if the presence of oxygen alters the quantum yield (which is also not reported). At the bare minimum, the treatment of the solution with relation to deaeration or not should be specified
6. page 2, line 99, what does TLC control mean? Do you mean as indicated by TLC monitoring of the disappearance of starting materials? Reword or specify what this means in a different way
7. page 2, line 109; the units of nm after 560 are shown as HM; fix to show as nm for nanometers
8. table 2: second column indicates wavelength with a label of (LE); this is a nonstandard abbreviation for what? explain or replace
9. add a comparison of a related system (yield, conditions, temp, catalyst loading, anything) for the discussion of the synthesis of the title compound
10. add a comparison of the abs and emission data of the title compound with a related system

also related to the luminescence; no mention is made of whether the solution was deaerated or not, as the presence of oxygen might also likely be the cause of your very weak emission intensity. It may be worth collecting an emission spectrum of a deaerated solution to see if the presence of oxygen alters the quantum yield (which is also not reported). At the bare minimum, the treatment of the solution with relation to deaeration or not should be specified
Response from authors.
The measurements were carried out in deaerated methylene chloride, and the results were the same as in the case of using a non-deaerated solvent. The reason for the low luminescence intensity was the manifestation of non-radiative relaxation, which led to quenching of the luminescence.
