  Synthesis and structures of thieno[2,3-b]thiophene incorporated [3.3]dithiacyclophanes. Enhanced first hyperpolarizability in an unsymmetrically polarized cyclophane

  摘要：

  Dithiacyclophanes incorporating thieno[2,3-b]thiophene have been synthesized. in order to investigate the nonlinear optical properties of donor-acceptor cyclophane 7. Cyclophane 7 displayed significantly higher first hyperpolarizability beta (21.6 x 10(-30) esu) compared to model 10 (9.58 x 10(-30) esu). Relatively higher in 7 presumably arises from an extra electron redistribution arising from through-space charge transfer, a feature lacking in 10. Moreover. the thermal decomposition temperature of 7 (300 degrees C) is higher than that reported for the NLO prototype DAN (295 degrees C). (c) 2006 Elsevier Ltd. All rights reserved.
