标题:Trialkylsilylethynyl-Substituted Triphenylenes And Hexabenzocoronenes: Highly Soluble Liquid Crystalline Materials And Their Hole Transport Abilities
摘要:Four Triphenylene (Tp) And Four Hexa-Peri-Hexabenzocoronene (Hbc) Derivatives With Trialkylsilylethynyl Groups Were Prepared And Characterized By Differential Scanning Calorimetry,Polarizing Optical Microscopy,And X-Ray Diffraction Measurements. All Compounds Were Highly Soluble In Less-Polar Organic Solvents And Exhibited A Columnar Phase,Col(H) Or Col(R) For The Tps,And Col(H) For The Hbcs. The Hole Transport Ability In The Hbcs' Columnar Phase,0.4-1.5X10(-3) Cm(2) V-1 S(-1) At 40-180 Degrees C,And Its Temperature Dependence Were Determined By The Time-Of-Flight Method Using A Solution Technique.
