Abstract
An efficient synthetic route (target products obtained with yields 65–85%) for obtaining of malononitrile derivatives containing triazole motif substituted in the way providing the electronic architecture Acceptor-π-Acceptor-Acceptor/Donor (–CH2(CN)2/–C6H4–/triazole/substituent) is presented. As the substituents phenyl (A1), p-pentyloxyphenyl (A2), pyrid-2-yl (A3), 9,9-dimethylfluoren-2-yl (A4), 9-octyl-9H-carbazol-3-yl (A5), dibenzo[b,d]thiophen-2-yl (A6) and 2,2′-bithiophenyl-5-yl (A7) were used. The structures of compounds were confirmed by 1H and 13C NMR spectroscopy. The thermal, optical and photophysical properties of obtained target compounds were checked. Understanding of obtained data was supported by quantum-chemical calculations based on DFT methods (time-dependent calculations, NTO analysis, structural parameters). Moreover, the druglikeness analysis was performed based on the commonly known rules.
