  A model of phantom scalar field dark energy under exponential potential
coupling to barotropic dark matter fluid in loop quantum cosmology is addressed
here. We derive a closed-autonomous system for cosmological dynamics in this
scenario. The expansion in loop quantum universe has a bounce even in presence
of the phantom field. The greater decaying from dark matter to dark phantom
energy results in greater energy storing in the phantom field. This results in
further turning point of the field. Greater coupling also delays bouncing time.
In the case of phantom decaying, oscillation in phantom density makes small
oscillation in the increasing matter density.
