wherein A is a group having at least one electron-withdrawing group, and for any of the structures, when one or more of Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, Rv and Rw occur, at least one of Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, Rv and Rw is a group having at least one electron-withdrawing group;
optionally, the group having at least one electron-withdrawing group is selected from a group consisting of: F, CF3, OCF3, SF5, SO2CF3, a cyano group, an isocyano group, SCN, OCN, a pentafluorophenyl group, a 4-cyanotetrafluorophenyl group, a tetrafluoropyridyl group, a pyrimidyl group, a triazinyl group, and combinations thereof;
