Supramolecularchirality and liquid crystalline OFET: Achiral end‐capped oligothiophenes can be tuned to exhibit supramolecularchirality with unique striped textures showing distinct circular dichroism signals as well as a highly ordered SmE phase that leads to high hole carriermobility.

A facile and efficient protocol for the synthesis of oligophenylene OPP(n)-substituted calix[4]arenes (with n up to 4) via iodo-substituted oligoarylcalix[4]arenes has been developed. The cooperation effect of the proximate fluoroionophores in hexylsulfanyl end-capped OPP(n)-substituted calix[4]arene assemblies leads to metal ion binding enhancement.

A novel-series of two-dimensional pi-conjugated oligoarylenes has been synthesized by a divergent approach using Pd-catalysed Suzuki cross-coupling of tetraiodophenylbenzene and arylboronic acid as a key step. It has been shown that the 'X-branched' structure can provide a useful platform to construct amorphous molecular materials as it can enhance the morphological and thermal stability as well as to facilitate solubility and processibility of a material when compared to those of the corresponding linear oligomers. The diphenylamino end-capped two-dimensional oligoarylenes were found useful as a hole transporting/emitting layer for light emitting applications. (c) 2005 Elsevier Ltd. All rights reserved.
