Novel pseudo-Frechet-type dendrons with 1,3,5-triazine structure G1.0(NOT) and G2.0(NOT) were synthesized under mild conditions by cyanuric chloride, beta-naphthol, and 3,5-dihydroxybenzyl alcohol with the yields of 96.3 and 85.6%. The structure of the dendrons was characterized by elementary analysis, IR spectrum, H-1-NMR, and FAB-MS. The dendrons had good thermo stability and solubility. They could partially transfer their absorbed energy to Eu3+, ion in tetrahydrofuran/acetone solutions. When the concentration of G1.0(NOT), G2.0(NOT), and Eu3+ ion was 5 x 10(-4) mol/L, G1.0(NOT) could enhance the fluorescent intensity of Eu3+ ion at 613 nm by 4.2-fold, whereas G2.0(NOT) could enhance the fluorescent intensity of Eu3+ ion at 465 and 613 nm by 18.6- and 11.7-fold, respectively.
