Abstract :
We report about the possibility to drive mass migration into an azo-based polymer by means of two-photon absorption. A symmetric donor-acceptor-donor structured Y-shape azo-chromophore is specifically synthesized to enhance two-photon absorption in the polymer. Features resulting from two-photon absorption in the near infrared show sub-diffraction limit linear dimensions (250nm).
