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.
