The absorption and fluorescence spectral characteristics of 4-hydroxy-3-methoxybenzaldehyde (HMB) have been studied in different solvents, pH and beta-cyclodextrin (beta-CD) and compared with 4-hydroxy-3,5-dimethoxybenzaldehyde (HDMB). The inclusion complex of HMB with beta-CD is analysed by UV-vis,
The inclusion complexation of 2-hydroxy-3-methoxybenzaldehyde (2HMB), 4-hydroxy-3-methoxybenzaldehyde (4HMB), 3,4-dimethoxybenzaldehyde (DMB) and 4-hydroxy-3,5-dimethoxybenzaldehyde (HDMB) with α-CD, β-CD, HP-α-CD and HP-β-CD were carried out by UV-Visible, steady-state and time-resolved
