the effect of fluoroalkyl chain on the mesomorphism. Several homologues of novel triphenylene compounds possessing fluoroalkylated side chains were synthesized. Studies of X-ray diffraction, DSC and texture observations by polarized microscope revealed that these homologues show hexagonal columnar (Colh) mesophase. These homologues made columnar mesophase stabilize and the melting point increase, as compared
该报告讨论了氟烷基链对同构作用的影响。合成了具有氟烷基化侧链的新型三亚苯基化合物的几个同系物。通过偏光显微镜对X射线衍射,DSC和织构观察的研究表明,这些同系物显示出六方柱状(Col h)中间相。与相应的烷氧基三亚苯基相比,这些同系物使柱状中间相稳定并且熔点增加。在具有氟亚甲基侧链的氟代烷氧基三亚苯基的情况下,氟亚甲基链长的增加稳定了柱状中间相,使相变焓(Col h -Iso)和熵(Col h-Iso)增加。认为这些结果是由于亲氟相互作用,并且亲氟相互作用对于稳定柱状中间相是重要的。
Charged Carrier Mobility Study in Col<sub>h</sub> Mesophase of Perfluoroalkylated Triphenylene Derivatives
The charged carrier mobility was measured for a Col(hd) mesophase of a perfuluoroalkylated triphenylene derivative to compare that of the corresponding non-fluorinated alkoxy derivative. The mobility was determined for both positive and negative charges which is in the order of 10(-4) cm(2) V-1 s(-1). In the negative electrode inllumination, the transient photocurrent decay carves consist of the fast and slow components and the latter is probably derived from an ionic transport. Though the perfluoroalkylated triphenylene shows the higher thermal stability of a Colhd mesophase, than the corresponding hydrogen homolougue, the mobility is in the same order and the ambipolar character is shared.

Preparation of Fluorous DMF Solvents and Their Use for Some Pd-catalyzed Cross-coupling Reactions

N,N-Dimethylformamide derivatives 1a (Rf6-DMF) and 1b (Rf8-DMF) with a C6 or C8 fluorous ponytail, respectively, have been synthesized and examined for some physical properties. Rf6-DMF was tested as a solvent for Mizoroki–Heck arylation of butyl acrylate and Sonogashira coupling reaction of iodobenzene with phenylacetylene. Both reactions proceeded as smoothly as in DMF to give the products in high yield. Fluorous DMF derivative 1a can be recovered easily from the reaction mixture by a fluorous/organic biphasic workup and recycled.
