Rinkesh Patel, Dhaval Gajjar, Hema Patel and Pravinkumar M. Patel

Hydroxyl terminated triazine based dendrimers were synthesized up to generation 2 using N,N’- bis(4,6-dichloro-1,3,5-triazin-2-yl)butane-1,4-diamine as core by divergent method. Core and half generation dendrimer (G1.5) were chlorine terminated and full generation dendrimers (G1) and (G2) were hydroxyl terminated. Synthesized dendrimer generations were characterized by FT-IR, 1 H-NMR, 13C-NMR, ESI-Mass spectrometry and elemental analysis. Intrinsic viscosities of full generation dendrimer G1 and G2 were determined and hydrodynamic radii were calculated. Thermal properties of full generation dendrimers were investigated by thermo gravimetric analysis. Doyle’s method was applied for evaluation of thermogravimetric data. Glass transition temperatures of dendrimer generations were determined by differential scanning calorimetry.
