摘要	A new type of hydrogen-bonded layer-by-layer (LBL) photoalignment film was fabricated and studied. The photosensitive hydrogen donor containing cinnamoyl groups (Poly (4-acryloyloxy)-cinnamic acid, (PCA) was self-assembled with hydrogen accepter poly (4-vinylpyridine) (PVPy) in an organic solvent. Then a hydrogen-bonding directed ultrathin film was formed. The uniformity and linear growth of the deposition procedure was proven by UV-Vis spectra and the interaction between PVPy and PCA was identified as hydrogen bonding using FT-IR spectroscopy. When linearly polarized ultraviolet light (LPUVL) irradiated the multilayer film, only the photosensitive double bond parallel to the polarization direction of LPUVL could be polymerized via [2+2] cycloaddition. After the irradiation an anisotropic film was prepared, and we used this anisotropic film as an alignment layer of nematic liquid crystals, and obtained uniform and stable alignment results.
