| Abstract: | Interaction between cucurbit 7 ] uril and tricyclazole in aqueous solution were investigated by UV - Vis spectra. The effects of temperature on the stability and thermodynamic parameters of the system were further studied in the current work. The results showed that the inclusion complex formed between cucurbit 7] uril and tricyclazole, whose stability constant and thermodynamic parameters were （9.23 ± 0. 05 ） ×10^3 L/mol, △G（ -2.26 ×10^4 J/mol）, △H0（ -43.79 J/mol） and △S0（ -72.78 J/K · mol）. The complexation of tricyclazole with Q 7 ] improved the antimicrobial activity （ 16% ） of trieyclazole against Magnaporthe grisea in vivo. |
