Tetraphenyl siloxanediolate

Figure 5. Photoluminescence emission spectra of the stereoregular phenylcyclo-siloxanes, [PhSi(0SiMe3)0], w = 4, 6, 8, 12, together with the linear tetraphenyl-1,3-siloxanediol, measured (in powder form) at the temperature of liquid nitrogen, T-71K. Excitation wavelength 280 nm, spectral bandwidth ca. 2 nm, edge filter (370 nm). D2 linear D4 =4 D6 =6 D8 =8 D12 n=l2.
