We present new mechanism of liquid crystal photoalignment based on reversible intermolecular bonds (hydrogen bonds or metal‐oxygen bonds) between dye molecules. This mechanism differs from known before and possesses temporal stability of photoinduced alignment against thermal disordering at room temperature. Predicted photoalignment dye was synthesized and verified in experiment.
