In this work we present electropolymerization of monomers of an unusual type using N-linked carbazole units to limit their conjugation. The polymers thus obtained have limited conjugation through the backbone. Using donor-acceptor-donor (D-AD) and donor-donor-donor (D-D-D) monomers we evaluate the effects of the presence (or absence) of charge transfer states on synthesized electropolymers. The use of a D-AD monomer resulted in obtaining an ambipolar polymer with quasi-reversible reduction. Reviewers' comments: Reviewer #1: This is a nice paper which deserves publication. The synthetic part as well as the electrochemistry is sound and well done, and the new monomers are interesting. On the other hand, the spectroscopic part is too short. What is the fluo QY of the monomers ? Do the polymer fluoresce (and in which state) ? A table gathering all this would be welcome. Even if a detailed paper on fluorescence is being written, though a couple of details would be welcome in the present article. A table showing basic photophysical data (including PL) has been attached to the manuscript. Polymers are not god emitters due to the fact that we cannot obtain fully undoped, purified polymers(oligomers), as the films are insoluble. We have only been able to observe luminescence from poly(2), however, as the paper is focused on electrochemistry, we decided not to include this observation here. PLQY's shown in the work were measured in methylcyclohexane and all the spectroscopic part modified in order to adapt the changes. Cyclohexane and methylcyclohexane are very similar solvents so the results are in fact not affected by the change. Please note that I do not comment on the ESR section, which is outside my expertise. Reviewer #2: This manuscript by P. Data describes the electrochemistry and spectroelectrochemistry of two polymers. I think this paper can be reconsidered after addressing the following points: 1. Would the authors show practical applications of poly(1) and poly(2) as emitting layers in polymer light emitting diodes? I don't think that poly(2) is a promising emitting layer in polymer light emitting diodes. The carbonyl group in acridone unit serves as a fluorescence quenching unit. To make it more precise: we suggest only poly(2) to be used as OLED emitter, but not poly(1). Poly(1) and monomer 1 in general contain fluorescence-quenching phenoxazine that in fact eliminates the use of such a system as an emitter, however poly(2) and monomer 2 contain acridone that in fact is known as an efficient fluorescence emitter. Moreover, there are some examples of D-AD molecules with acridone unit that show
