摘要
含共轭侧链的引达省并二噻吩分别与1,3-茚满二酮和3-乙基绕丹宁构筑小分子WS1和WS2。通过核磁共振(氢谱和碳谱)和飞行时间质谱对目标小分子进行结构表征。通过测试目标小分子的吸收光谱和循环伏安曲线,研究末端的种类对小分子的光物理性质和电化学性质的影响。结果表明,末端为1,3-茚满二酮的WS1具有更加宽的吸收光谱(最大吸收峰达到567nm);WS1和WS2具有相当的能级,说明末端的种类对小分子的能级影响不大,-5.45 eV的HOMO能级水平能够与常见的受体材料匹配。
Two small molecules WS1 and WS2 were constructed by the indacenodithiophene containing the conjugated side chain and the different end units, 1,3-indanedione and 3-ethyl rhodamine, respectively. Structural characterization of the small molecules by nuclear magnetic resonance(1 H-NMR and 13 C-NMR) and time of flight mass spectrometer(TOF). The effects of the kinds of end unit on the photophysical and electrochemical properties of small molecules were investigated by testing the absorption spectra and cyclic voltammetry curves. The results show that WS1 with 1,3-indanedion had a broader absorption spectrum(maximum absorption peak reaches 567 nm);WS1 and WS2 had nearby energy levels, indicating the effect of terminal units on the energy level, and their HOMO level of-5.55 eV was matched to common acceptor materials.
