英文摘要	<正> The microenvironmental effects of β-cyclodextrin (β-CD) on the twisted intramolecular charge transfer (TICT) of ρ-N, N-dimethylaminobenzaldehyde (DMABA) are investigated using fluorescence spectroscopy. The typical TICT dual fluorescence of DMABA is observed in pure water and aqueous β-CD solution, and β-CD has s remarkable influence on the TICT fluorescence characteristics of DMABA. A linear dependence of the ratio of intensity of TICT fluorescence band (a band) to that of normal fluorescence band (b band) on DMABA concentration is also observed and the introduction of β-CD increases the linear slope. Combined with the results of absorption spectroscopy, fluorescence polarization, and peculiar salt effects, the properties of TICT state of DMABA, the interaction of DMABA with β-CD, and the intrinsic traits of the microenvironmental effects of β-CD are discussed in detail.
