 The CPO1 chromophore, after transformation, was grafted on a Xu-DR1 hyperbranched polyimide polymer. It led to a new high-performing electro-optic material. The resulting new polymer has a high glass temperature transition. It was sandwiched as a 3 µm thick film between electrodes and characterized by an r33 nonlinear quadratic susceptibility coefficient around 40 pm/V at 1.5 µm. It exhibits an electro-activity stable until 105°C. These performances are higher to those of a linear polymer.
