<p>A dye-modified cyclodextrin film, such as a medicinal wafer or other packaging film (for example, films for packing food and medicine, and package that upon leakage of food, exhibits a color change), whose wide application to pharmaceuticals, foods, agricultural chemicals, etc. is promising. There is provided a dye-modified cyclodextrin film comprised of a dye-modified cyclodextrin resulting from modification of a-cyclodextrin with p-methyl red, wherein the p-methyl red has a structure enclosed by the a-cyclodextrin of a cyclodextrin modified with a dye other than the p-methyl red, so that dye-modified cyclodextrin molecules accomplish high-order linkage to each other to thereby form a molecular assembly.</p> |
