    摘要:
    制备了大量含有2,5-二取代噻吩环的新型液晶,并研究了它们的介晶行为,以系统地探讨不同形状、极化能力和极性的噻吩衍生物的分子结构与介晶性之间的关联。通过这些研究,我们合成了一类新型液晶,它们含有2,5-二取代噻吩环和末端链中的共轭反式碳-碳双键。这些新颖的噻吩衍生物是首批在室温下表现出向列相的含有2,5-二取代噻吩环的液晶。这使得弯曲形状分子的挠曲电系数能够首次在作者所知的情况下直接在室温下测量。许多这些新型噻吩具有高双折射率和高向列相清亮点,有可能作为液晶显示器中向列相混合物的成分。

    A large number of new liquid crystals incorporating the 2,5-disubstituted thiophene ring have been prepared and their mesomorphic behaviour studied in order to systematically investigate the correlation between the molecular structure and mesomorphism of thiophene derivatives with different shapes, polarisability and polarity. As a consequence of these investigations we have prepared a new class of liquid crystals incorporating a 2,5-disubstituted thiophene ring and a conjugated trans-carbon–carbon double bond in the terminal chain. These novel thiophene derivatives are the first liquid crystals incorporating a 2,5-disubstituted thiophene ring to exhibit a nematic phase at room temperature. This enables the flexoelectric coefficients of a bent-shaped molecule to be measured directly and at room temperature for the first time to the authors' knowledge. Many of these new thiophenes exhibit a high birefringence and a high nematic clearing point and are of potential use as components of nematic mixtures in LCDs.

    A novel heterogeneous catalyst (Cu NPs‐OMCN) was synthesized and utilized as a highly efficient catalyst for homo‐ and cross‐coupling of terminal alkynes under base‐free conditions in ethanol. Various symmetrical and unsymmetrical 1,3‐diynes were obtained with good to excellent yields. Furthermore, the heterogeneous catalyst could be recovered and reused for several times with satisfactory yields.
