Liquid–crystalline perylene tetracarboxylic acid bisimide bearing oligosiloxane chains with high electron mobility and solubility
摘要:
Liquid-crystalline perylene tetracarboxylic acid bisimide derivatives 1 and 2 bearing 1,1,1,2,2,3,3-heptamethyltrisiloxane chains at the end of alkyl side-chains have been synthesized. Compound 1 having four trisiloxane chains exhibits a hexagonal columnar phase at room temperature. Time-of-flight measurement reveals that the electron mobility in the columnar phase of compound 1 exceeds 10 (3) cm(2) V (1) s (1) at room temperature. In contrast, compound 2 bearing two trisiloxane chains is not mesomorphic. These two compounds are soluble in various organic solvents except for alcohols and thin films can be produced by a spin-coating method. (C) 2012 Elsevier B. V. All rights reserved.

Liquid-crystalline perylene tetracarboxylic bisimide derivatives bearing heptamethylcyclotetrasiloxane moieties have been synthesized. Compound 2 bearing four heptamethylcyclotetrasiloxane moieties exhibits a rectangular columnar phase at room temperature. In the columnar phase, the cyclotetrasiloxane rings interdigitate into neighbouring columns and their interaction promotes the formation of the columnar mesomorphic structure. A time-of-flight measurement reveals that the electron mobility in the columnar phase of compound 2 is on the order of 10−2 cm2 V−1 s−1 at room temperature. Compound 2 is soluble in various organic solvents except for alcohol.
