Abstract: By using G09 program package, the absorption and fluorescence/phosphorescence spectra of dipterex were explored, and its spectroscopic characters were altered by methacrylic acid (MAA) as the imprinted molecule. The TD-DFT results revealed that: (1) All absorption and emission excitations of dipterex are assigned to the nσ* transition; (2) without MAA as imprinted molecule, one of the dipterex CCl bonds is extended significantly and dipterex is almost destroyed in transition states; (3) dipterex is connected to methacrylic acid via two hydrogen bonds; (4) for the dipterexGÇôMAA complex, the electronic excitation (ππ* excitation) in absorption spectra is dominated by the configuration HOMO -> LUMO
