Triaryl-1,3,5-triazinane-2,4,6-triones functionalized with electron-rich Fe(ii) and Ru(ii) acetylide complexes: new organometallic octupoles with large hyperpolarizabilities

Abstract

The synthesis and study of a series of trinuclear organometallic triaryl-1,3,5-triazinane-2,4,6-triones functionalized by d(6)-transition metal acetylides complexes at their periphery are reported. Remarkably large hyperpolarizabilities, far superior to those of related purely organic derivatives, are measured by hyper-Rayleigh scattering (HRS) for these new octupolar chromophores.
