Birefringence in guest–host Ru-containing chromophore induced by acoustic field

We have observed firstly a difference in birefringence caused by left- and right-handled circularly polarized acoustical fields for organometallic racemic tris(phenanthroline)ruthenium(II) dichloride chromophore incorporated within the polymethacrylate polymer. Within the acoustic power densities 1....

Description
Summary:We have observed firstly a difference in birefringence caused by left- and right-handled circularly polarized acoustical fields for organometallic racemic tris(phenanthroline)ruthenium(II) dichloride chromophore incorporated within the polymethacrylate polymer. Within the acoustic power densities 1.2–2.2 W/cm 2, this difference substantially increases up to the birefringence value of about 0.003. After the switching off of the acoustical field, the induced birefringence disappears after 14 s birefringence decay kinetics after switching off the acoustic field consists from two parts (at 8 and 14 s).
