Exfoliated semiconducting MoS2 and WS2 were covalently functionalized with 1,2-dithiolane-modified carbon nanodots (CNDs). Based on electronic absorption and fluorescence emission spectroscopy, modulation of the optoelectronic properties of transition metal dichalcogenides (TMDs) by interfacing with CNDs was accomplished.

Ammonium modified MoS2 and WS2 were prepared and characterized by complementary spectroscopic, thermal and microscopic means. The positive charges on functionalized MoS2 and WS2, owed to the presence of ammonium units, were exploited to electrostatically bring in contact an anionic porphyrin bearing a carboxylate moiety, yielding porphyrin/MoS2 and porphyrin/WS2 nanoensembles, respectively.
Recent advances in large-scale production of graphene have led to the availability of solution-processable platelets at the commercial scale. Langmuir-Schaefer (L-S) deposition is a scalable process for forming a percolating film of graphene platelets which can be used for electronic gas sensing. Here, we demonstrate the use of this deposition method to produce functional gas…

Maser Advanced Functional Materials, 2018, 1707548 The game‐changing role of graphene oxide (GO) in tuning the excitonic behavior of conjugated polymer nanoparticles is described for the first time. This is demonstrated by using poly(3‐hexylthiophene) (P3HT) as…
The preparation, characterization and photophysical and electrocatalytic properties of carbon nanodots (CNDs)/MoS2 ensembles were reported. Based on electrostatic interactions, ammonium functionalized MoS2, prepared upon reaction of 1,2-dithiolane tert-butyl carbamate with MoS2 followed by acidic deprotection, was coupled with CNDs bearing multiple carboxylates on their periphery as derived upon microwave-assisted polycondensation of citric acid and ethylenediamine…
