Investigation of Cage Effect of Water-Solub Dendrimers as Microreactors
摘要
Abstract
The a-cleavage photoreactionof 1-phenyl-3-p-tolyl-propan-2-one(CH3-DBK) hasbeen conductedin aqueoussolutions of water-soluble poly (aryl ether) dendrimers Gn (n =1-4) and PAMAM dendrimers PGm(m=7-3). The product distributionreveals that dendrimers can provide a more constrained microenvironment than the homogenous solutions. The cage effect increases with the generation of Gn, indicative of a better confined microenvironment of higher generation Cm. The cage effect can also be enhanced by increasing the concentration of dendrimer. PGm(m= 1-3) have much less constrained microenvironment, consequently exhibit low cage effect.关键词
