Abstract:
Novel poly(amidoamine) (PAMAM) dendrimer is designed and synthesized via a divergent method based on perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) as a luminescent core. Iterative Michael addition and amidation reactions were used to synthesize PTCDI-based PAMAM dendrimer. Due to the photo-induced electron transfer (PET), these systems are configured as a “fluorophore-spacer-receptor”. The structures of PTCDI-core PAMAM dendrimers were characterized using Fourier transform infrared (FT-IR). Fluorescence microscopy (FM) and fluorescence spectrophotometer (FL) were used to observe fluorescent properties and emission amounts of the luminescent core-PAMAM. The results showed that by increasing branches on the PTCDI core the fluorescence emission of dyes increased.
