Quantum mechanism calculations were performed to study the relationship between strength of electron-donating, electron-withdrawing groups and electronic, photochemical, charge transport properties. Electron-donating groups blueshifted the ultraviolet (UV)/visible spectra, while electron-withdrawing groups redshifted the UV/visible spectra. Inverse relationship observes between Hammett parameter and reorganization energy. Small molecules acceptors with electron-withdrawing substituents showed higher electron mobility. This study can pave way for experimental chemists to synthesize efficient small molecule acceptors.

“…From recent few years, performance of nonfullerene acceptors (NFAs) has been significantly improved. Comparative to competitors, they have unique advantages such as easily tunable chemical structures, low cost synthesis and strong absorption in broad range [10][11][12][13][14] . Non-fullerene small molecule acceptors are designed by suitable combination of electron-rich and electron-deficient groups.…”

End groups plays very important role to tune the properties and performance of small molecule acceptors. In this study, theoretical analysis was performed to find the reason why two similar molecule differ in end-group showed much different performance in organic solar cells. 1,1-dicyanomethylene-3-indanone based small molecule acceptor (DC-IDT2Tz) showed higher transition dipole moment as compare with malononitrile based small acceptor (MN-IDT2Tz). DC-IDT2Tz showed lower exciton binding energy as compare to MN-IDT2Tz. As well as, DC-IDT2Tz showed lower reorganization energy and higher transfer integral as compare with that of MN-IDT2Tz. All the theoretical descriptors are explaining reason behind the higher efficiency of DC-IDT2Tz. Studying theoretical parameters can help to check the performance of organic semi-conductor before synthesis. This work will be helpful for experimental scientists to screen the compounds and to select best one for synthesis.

“…Arylazo dyes of different heterocyclic moieties have been reported in the recent literature as the subject of intense research by chemists [8] and dye manufacturers [9]. Azo-thiophene and azo-thiazole derivatives have received significant attentions since they are applied in dye-sensitized solar cells and as efficient semiconducting materials [10][11][12][13][14]. successfully a series of thienylazo-thiazole and thienylazo-thiophene derivatives by utilization of 2-amino-4,5,6,7-tetrahydrobenzo[b]thiophenes as diazo-components and their diazo-coupling with 2-aminothiazoles and 2-acetyl-3-oxo-Nphenylbutane-thioamide as coupler components.…”

F ACILE synthesis of various thienylazo-thiazole and thienylazo-thiophene dyes were described. 2-Amino-5-(2-thienylazo)-thiazole dyes 5 and 6 have been constructed by coupling the diazotized 2-aminothiophenes 1a and/or 1b with 2-amino-4-phenylthiazole (3) and/or 2-(N-methylamino)-4-phenylthiazole (4). Coupling of 2-aminothiophene derivative 1a with 2-acetyl-3-oxo-N-phenylbutanethioamide (7) affected cleavage of one acetyl group to furnish the corresponding 2-acetyl-2-thienylazo-thioacetanilide dye 8 which has been utilized as a precursor for the construction of different 3-methyl-2-substituted-4-thienylazo-thiophenes 10-13 through its treatment with the appropriate alpha-chlorinated reagents (namely; MeCOCH 2 Cl, PhCOCH 2 Cl, ClCH 2 COOEt and ClCH 2 CN). The effect of solvent polarity on absorption spectra was investigated, as was the relationship between dye structures and absorption in the UV-visible region.
