Abstract

A novel rigid and planar chromophore, p-phenylene benzobisthiazole unit with donor and acceptor groups, has been synthesized for second-order nonlinear optical applications. The first hyperpolarizability, β, of the nonlinear optical (NLO) chromophore has been measured by a Hyper-Rayleigh Scattering technique at 1064 nm in 1,1,1,3,3,3-hexafluoro-2-propanol solution. The β value of the NLO chromophore is 405E-30 esu, which is about seventeen times that of the p-NA (nitroaniline) value. The chromophore showed good thermal stability up to 330 °C in nitrogen atmosphere.

3.Compound 2, BB10.21.4 2,5-Bis[(2-cyanoethyl)thio]-N-(p-dimethylaminobenzyl)-N'-(p-nitrobenzyl)-p-phenylenedia mine, was synthesized by the following procedure: Et3N (0.61 g, 6 mmol) was added to a stirred solution of 1 (2.57 g, 5 mmol) in 20mL of NMP at room temperature under argon. To this solution, 4-dimethylamino benzoyl chloride (1.10 g, 6 mmol) in 10 mL of NMP was slowly added dropwise with vigorous stirring at 0 °C under argon. The mixture was stirred overnight (16 h) from 0 °C to room temperature. The product was isolated by pouring the solution into 900 mL of water. Recrystallization from acetone afforded 2.65 g (92 %) of pure 2 as yellow powder: 1H NMR (DMSO-d 6) δ: 2.78 (t, 2H, J = 6.6 Hz), 2.80 (t, 2H, J = 6.6 Hz), 3.01 (s, 6H), 3.18 (t, 2H, J = 7.2 Hz), 3.19 (t, 2H, J = 7.2 Hz), 6.78 (d, 2H, J = 9.4 Hz), 7.64 (s, 1H), 7.82 (s, 1H), 7.87 (d, 2H, J = 8.8 Hz), 8.23 (d, 2H, J = 8.3 Hz), 8.40 (d, 2H, J = 8.8 Hz), 9.65 (s, 1H), 10.43 (s, 1H); 13C NMR (DMSO-d 6) δ: 17.83, 29.49, 42.15, 111.48, 119.65, 124.24, 127.05, 128.56, 129.73, 131.40, 134.58, 137.67, 140.26, 149.91, 153.14, 164.69, 165.68.

4.Compound 3, 2-(4-dimethylaminophenyl)-6-(4-nitrophenyl)benzo(1,2-d:4,5-d')bisthiazole, was synthesized by the following procedure: 2 (0.57 g, 1 mmol) was added to a stirred solution of 0.4 g of P2O5 in 2 mL of methanesulfonic acid at room temperature under argon. The mixture was heated at 80 °C for 12 h, 100 °C for 12 h and further at 120 °C for 12h. The solution was cooled to room temperature and poured into ice water. The solid mixture was neutalized with saturated aqueous NaHCO3. The resulting precipitate was collected by filtration and washed with water/methanol. The crude product was purified by recrystallization from dimethylsulfoxide (DMSO) to give the required chromophore 0.16 g (38 %): 1H NMR (CF3COOD) δ: 3.61 (s, 6H), 8.11 (d, 2H, J = 7.7 Hz), 8.44 (d, 2H, J = 8.8 Hz), 8.51 (d, 2H, J = 7.7 Hz), 8.65 (d, 2H, J = 8.8 Hz), 9.22 (s, 1H), 9.29 (s, 1H); 13C NMR (CF3COOD) δ: 47.01, 114.31, 122.41, 125.15, 129.37, 129.84, 131.42, 132.89, 133.20, 134.32, 143.05, 144.70, 146.85, 151.20, 175.29.
