  Liquid-Crystalline Properties of Poly(propylene imine) Dendrimers Functionalized with Cyanobiphenyl Mesogens at the Periphery

  摘要：

  Three generations poly(propylene imine) dendrimers with 4, 16, and 64 terminal amine groups have been functionalized with pentyloxycyanobiphenyl and decyloxycyanobiphenyl mesogens. The liquid-crystalline properties of these dendrimers have been studied in detail by differential scanning calorimetry, optical polarization microscopy, and X-ray diffraction. All the mesogenic dendrimers orient into a smectic A mesophase. Thermal properties are influenced to a large extent by the spacer length, showing g-->S-A-->I transitions for the dendritic mesogens with the pentyloxy spacers and K-->S-A -->I transitions for the ones with a decyloxy spacer. In the latter, the temperature range of the mesophase increases with dendrimer generation. Mesophase formation in the case of the pentyloxy series is more difficult compared with the corresponding decyloxy analogues, when the transition enthalpies and the kinetics of obtaining microscopic textures are considered. The effect of generation on mesophase formation cannot be clearly distinguished, although in the case of the fifth-generation dendrimer with a decyloxy spacer, microscopic textures could be obtained more easily, compared with the lower generations. X-ray diffraction measurements of oriented samples indicate that the cyanobiphenyl endgroups of both series orient into an antiparallel-overlapping interdigitated structure. The observed S-A-layer spacings are independent of the dendrimer generation for both spacer lengths, indicating that the dendritic backbone has to adopt a completely distorted conformation, even for the higher generations.

  Formation of smectic and columnar liquid crystalline phases by cyclotriveratrylene (CTV) and cyclotetraveratrylene (CTTV) derivatives incorporating calamitic structural units

  摘要：

  新型的液晶寡聚介质，由五个、六个或八个 calamitic 4-氰基联苯、2-烷基-5-苯基-1,3,4-噻二唑或5-辛基-2-苯基嘧啶单元通过不同长度的间隔基与一个环三苯基中心核(CTV衍生物,2,3,7,8,12,13-六取代的10,15-二氢-5H-三苯并[a,d,g]环壬烯)或一个环四苯基中心核(CTTV衍生物,2,3,6,7,10,11,14,15-八取代的5,10,15,20-四氢四苯并[a,d,g,j]环十二碳四烯)共价连接而成，已被合成。这些化合物通过偏光显微镜、差示扫描量热法进行研究，其中一些还通过X射线衍射进行了研究。许多CTV衍生物显示出液晶性质。含长间隔基单元的氰基联苯衍生物具有固-液同质相(SA相)，可以很容易地过冷。噻二唑衍生物和嘧啶衍生物只有在间隔基单元相当短时才具有液晶相。噻二唑衍生物在CTV核与calamitic介质之间具有奇数连接原子时形成SA相，而具有偶数间隔基的噻二唑衍生物则显示柱状液晶相。我们提出，这些寡聚介质观察到的柱状液晶相并非因其能形成近似圆盘状的形态，而是代表带状相，这是由中心锥状核和棒状介质基团的不同空间填充引起的立体障碍造成的。假定具有偶数间隔基的分子呈现类似曲折(香蕉状)的平均形状，是形成带状相的原因。此外，一个具有八个附加苯基噻二唑介质的CTTV衍生物显示柱状液晶相。相应的氰基联苯衍生物发现有向列相，而嘧啶衍生物则不具有液晶性。
