“…Chalcones are ,-unsaturated carbonylic compounds, they constitute one of the major classes of flavonoids and isoflavonoids, with a widespread distribution in fruits and vegetables. They present inherent and exceptional antibacterial, antifungal, antitumor and anti-inflammatory properties [1][2][3][4][5][6][7]. In addition, to its intrinsic biological importance, these compounds have conjugated -systems, conferring interesting optical properties, including high extinction coefficients in the UV absorption region and a significant nonlinear optical response, thus they can be considered as: (1) promising candidates in the preparation of novel nonlinear optical (NLO) materials [8][9][10][11][12], (2) organic light emitting diodes (OLED) [13][14][15][16][17] and (3) electrochemical sensors [18][19][20].…”

We have studied the electronic and electrochemical properties of seven substituted heterocyclic chalcones (CHL 1-6) wich are functionalized with 2-thienyl groups. The phenyl ring of the chalcone scaffold has been substituted in orto or para position with electron donnor and acceptor groups (-F, -NO2, -CH3O). The electrochemical features were analyzed by cyclic voltammetry; irreversible processes were observed and attributed to the oxidation and reduction of the 2-thienyl group and the carbonyl group of the chalcone, respectively. DFT calculations were made to gain more in-depth understanding of their electronic properties. Relatively high HOMO level and low LUMO values were calculated, Eg values computed varies between 3.0-3.29 eV. These values enable us to postulate that these type of compounds are suitable building blocks to fabricate optoelectronic devices.
