In a one-pot reaction, three new 2,3-diaminomaleonitrile (DAMN) derivative dyes were prepared by simple Schiff base reaction. The compounds were designed as a sensitizer in dye synthesizes solar cells (DSSCs). Many conditions have been used to provide the methodology to get the best yield. The prepared dyes were characterized by melting point, elemental microanalysis, mass spectroscopy, FT-IR, 1H-NMR, and UV-Vis spectroscopy. A computational study was carried out to support our results. The DSSC data was shown the best performance for SA3 dye with 0.38% efficiency at AM 1.5 then SA2 with 0.22% and the last dye is SA1 with 0.09%, compared to control cell (N719) 5.4%.

This study including prepared new colored esters containing heterocyclic with high molecular weights. In the first part of work we synthesized azo dyes [1,2] from the reaction p-toluidine with β-naphthol and o-nitro phenol, thin we synthesized Schiff bases [3,4] by the reaction anthranilic acid with benzaldehyde and dimethyl benzaldehyde. The reaction azo dyes (contain OH group) with Schiff base (contain COOH group) these led to produce the new colored esters [A1-A4]. The second part of work was modification the (C=N-) group in esters to heterocyclic compounds by reacting with phenyl iso cyanide to produce new β-lactam [B1-B4] and with anthranilic acid to get new hydroquinazoline [C1-C4]. All these compounds were characterized by physical properties and spectral methods FTIR, 1H-NMR and 13C-NMR.
