  通过直接的Sonogashira偶联方法制备了新颖的烷氧基改性的2,7-二叔丁基-4,5,9,10-四（芳基乙炔基）py。通过UV / Vis和荧光测量研究了荧光团的光学性质，例如量子产率和吸收/发射光谱。通过存在特征性的红移的发射带和发射能力的降低，证明了在极性溶剂中和在固态下发色团的聚集诱导的准分子形成。这些结果有力地表明意外地观察到，相邻的芘环的受激准分子的形成不会被引入体积大的防止叔-丁基取代基。单晶X射线和计算分析揭示了molecules分子多聚芳烃的分子堆积中相邻分子的共面排列以及π-π堆积的存在。此外，荧光，DSC和POM测量表明，聚集行为，热特性和结晶特性会受到changing核外围附着的官能团结构变化的显着影响。

  A series of compounds has been prepared with 4-butylsulfanylphenyl and 4-cyano- or 4-isothiocyanato-phenyl units connected by -CHCH-, -COO-, -CC-, or -CC-COO- linking groups. The synthesis of the novel compounds is presented and the transition temperatures and optical parameters of the compounds are discussed and compared with those for related biphenyl reference systems. The ester linking group reduces optical and polarisability anisotropy, but the other linking groups give increased optical anisotropy (up to Δn = 0.50) and polarisability anisotropy [up to Δα = 45.2 Å3 (10−30 m3)].

  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.

  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。
