The invention is to provide a photosensitive compound suitable for a photoalignment method, a photosensitive polymer prepared from the compound, a photoaligning agent by using the compound and a liquid crystal alignment film prepared from the photoaligning agent. A photosensitive compound represented by formula (1):
in formula (1), Y1 is a divalent group represented by formula (2-1) or (2-2); A1 is 1,4-phenylene or 1,4-cyclohexylene; Z1 is a single bond, —COO— or —OCO—; R1 and R2 are each independently hydrogen, fluorine or alkyl having 1 to 5 carbons; Q1 is independently a single bond or alkylene having 1 to 12 carbons; and n is 0 or 1. In formulas (2-1) and (2-2), W1 and W2 are each independently hydrogen, alkyl having 1 to 3 carbons or alkoxy having 1 to 3 carbons.

structure and reactivity that can accompany the donor-acceptor arrangement in rigid beta-aminoketones. X-ray structural analysis of trione 6 and dione 7 reveals bond length and angle variations consistent with through-bond (hyperconjugative) donor-acceptor interactions. Observed is a shortening of the C-N bond, elongation of the central C-C bond (to approximately 1.6 A), and a significant pyramidalization
