Axis‐selective two‐photon excitation and polarization‐preserved triplet energy transfer using a linearly polarized (LP) 800 nm femtosecond pulse laser generates an anisotropic photoreaction in photocrosslinkable‐polymer liquid‐crystalline films. The molecular orientation is controlled parallel to the polarization of the laser. The tightly focused laser beam generates a submicrometer‐oriented structure, as shown in the Figure.
