- Abstract
- The monolayer behaviors of two dendrimers containing a hydrophilic core group (carboxy group) and hydrophobic branches (quinoxaline and methoxyphenyl groups), 2,3-bis{(4-[2,3-bis(4-methoxyphenyl)quinoxalin-6-yloxy]phenyl} quinoxaline-6-carboxylic acid (G2) and 2,3-bis[4-(2,3-bis{4-[2,3-bis(4-methoxyphenyl)quinoxalin-6-yloxy]phenyl} quinoxalin-6-yloxy)phenyl]quinoxaline-6-carboxylic acid (G3), were studied using surface pressure area (II-A) isotherms and atomic force microscopy (AFM). Surface pressure area isotherms show that the limiting area of G2 increased but G3 decreased on the europium ion-containing subphase than on the water subphase. The Langmuir-Blodgett (LB) films of dendrimer europium ion complexes preserve their original luminescent properties and the packing of further layers does not cause quenching of luminescence.
