Abstract:

We have designed two novel dendrimers with cyclam cores with appended poly(amido amine) (PAMAM) dendrons, decorated at the periphery with four and eight dansyl chromophores, respectively. The photophysical properties of the dendrimers and their Nd3+ complexes have been investigated. The energy-transfer efficiency to the lanthanide ions from these dendrimers has been studied as a function of the generation. It has been observed that an increase in the dendrimer generation as well as the number of amide units enhances the energy transfer to the lanthanide ion. Shine on: Two novel cyclam-core-based dendrimers with appended poly(amido amine) (PAMAM) dendrons, decorated at the periphery with four and eight dansyl chromophores, respectively, have been synthesized and characterized. Upon titration with Nd3+ it has been observed that an increase in the dendrimer generation as well as the number of amide units enhances the efficiency of the energy transfer to the lanthanide ion.
