A STUDY OF SOME BASIC LUMINESCENT PROPERTIES OF FIVE RELATED TETRAARYL SILANES UNDER ULTRA-VIOLET EXCITATION

Abstract

Some luminescent properties of the tetraaryl silane family composed of tetraphenyl silane, triphenyl-p-biphenylyl silane (silane I), diphenyl-di-p-biphenylyl silane (silane II), phenyl-tri-p-biphenylyl silane (silane III), and tetra-p-biphenylyl silane (silaneI (V) were investigated under conditions which minimized perturbations of the emission process. The fluorescence spectra of these 5 compounds at 298 and 77 K under UV excitation are reported; spectral structure was enhanced in the spectra of samples at 77 K. The similarity of the emission characteristics of the biphenylyl-substituted silanes to the corresponding characteristics of biphenyl suggests that the biphenylyl group is most responsible for luminescence in these four silanes.
