Abstract
The effects of cyclodextrins (α-CD,β-CD andγ-CD) on the photobleaching of coumarin 120 (7-amino-4-methylcoumarin) (1) and coumarin 151 (7-amino-4-trifluoromethylcoumarin) (2) have been investigated by spectrophotometric measurement. It is concluded thatβ-CD andγ-CD decelerate the rates of photobleaching of1, whilstγ-CD accelerates the rate of2 andβ-CD has no effect on the rate of photobleaching of2.
