We have investigated the formation of host–guest complexes between dendrimers of the poly(propylene amine) family functionalized with dansyl units at the periphery (hosts) with dye molecules (guests). Each dendrimer nD , where the generation number

A fourth generation POPAM dendrimer functionalized at the periphery with 32 dansyl groups (circles in the picture) can host up to six eosin dye molecules (black ovals) in two different sites (triangle, square). Efficient energy transfer processes fro

We have investigated the interaction of Co2+ ions (as nitrate salt) with dendrimers of the poly(propylene amine) family functionalized in the periphery with fluorescent dansyl units. Each dendrimer nD, where the generation number n goes from 1 to 5,

We report the preparation, absorption spectra, and photophysical properties (fluorescence spectrum, quantum yield, and lifetime) of five dendrimers of the poly(propylene amine) family (POPAMs) functionalized with dansyl units at the periphery. Each d

We report the synthesis of POPAM dendrimers, bearing up to 64 chromophores at their periphery. For these dendrimers, a radiotracer technique was used to study the liquid-liquid partition of pertechnetate and (14)C-labeled nucleotides in trichlorometh

Extending our stationary fluorescence and absorption measurements of petroleum products in cyclohexane solution, time-resolved measurements of the fluorescence decay are presented in this paper. Several parameters suitable for the description of fluo
