| With potential applications in advanced optoelectronic and all-optical data processing technologies, nonlinear optical (NLO) materials are currently of great interest, particularly those exhibiting second-order effects. Previous studies on 1D ruthenium ammine complexes have produced salts that possess very large NLO responses which can be reversibly switched via RuIII/II redox. 2D dipolar chromophores offer several potential advantages over their 1D counterparts, but almost all known 2D chromophores are charge neutral. The preparation of novel charged species may allow the “crystal engineering” of noncentrosymmetric materials suitable for bulk second-order NLO effects. We are engaged in the syntheses of dipolar C2v chromophores which feature a cis-{RuII(NH3)4}2+ electron donor centre connected to two N-methyl/arylpyridinium acceptor groups. The molecular electronic and NLO properties of these compounds have been studied by using a range of techniques including electronic Stark effect (electroabsorption) spectroscopy. |
