A particular advantage of the TR-PEEM approach, not shared by these more conventional embodiments of ultrafast microscopy, is the ability to image coherent phenomena in solids and surfaces. Because both the photoelectron excitation and imaging are sensitive to phases of both the excitation field and the electronic wavefunctions of the excited modes, a TR-PEEM experiment can uniquely probe coherent processes in solid-state materials. Coupling light with the electronic system creates a coherent polarization field comprising collective... 

These materials have been prepared by polymerisation of p-halothiophenoxide metal compounds both in the solid state and in solution. They have also been prepared by condensation of p-dichlorobenzene with elemental sulphur in the presence of sodium carbonate while the commercial polymers are said to be produced by the reaction of p-dichlorobenzene with sodium sulphide in a polar solvent.
