The 3rd Molecular Materials Meeting (M3) @ Singapore

Abstract

temperature-driven molecular self-organisation [1] to atom-transfer radical polymerisation based functional amphiphilic polymers synthesis, [2] from dye-sensitised solar cells [3] to nanoparticle-catalysed water-splitting, [4] from metal-organic frameworks [5] to aggregation-induced emission bioimaging, [6] etc. The second edition [Aust. J. Chem. 2012, 65 (9)] is however relatively focussed. It featured mainly on contributions in research of nanoparticles and organic energy materials. [7] The nanoparticle papers typified the harness of nanotechnology to enable new applications, e.g. using electro-responsive core-shell nanoparticles for rheology tuning, [8] carbon nanotube-based materials as catalysts in fuel cells, [9] using chitosan-functionalised Au/Pd alloy nanoparticles/nanoclusters for catalysis of aerobic oxidative homocoupling reactions, [10] and CdTe based hybrid fibres enabled low-voltage-driven electroluminescence devices, [11] etc; papers on organic semiconductor research focussed on the structure-property relationship that leads to design and synthesis of high performance molecular materials, e.g. heterocyclic dyes for efficient dye-sensitised solar cells, [12] phenyl-1H-pyrrole end-capped thiophenes for organic field-effect transistors, [13] and pyridine incorporated dihexylquaterthiophene as blue emitter in organic light emitting diode applications. [14] In this commemorative edition, seven papers are selected as highlights of the meeting. Bai et al. [15] (Institute of Materials Research and Engineering, Singapore) introduced a new dinuclear Cu(II) complex (Fig. 2) with 1,2,3-triazoles of a chelatebridging mode. Using rare azole-bridged ferromagnetically coupled dinuclear Cu(II) complexes as examples, the paper demonstrates the potential of using heterocyclic triazoles to support magnetically active dinuclear Cu(II) complexes. The finding marks a step closer to the establishment of magnetostructural relationship and understanding of magnetic exchange
