Propionic acid tethering hemicyanine dye molecules preferentially enter the channels of silicalite‐1 films with the head part first, in water in the presence of tetrabutylammonium hydroxide (this is shown schematically in the figure), giving rise to high‐concentration hemicyanine‐incorporating silicalite films with high second‐harmonic‐generation efficiency.
