Water-soluble perylene tetracarboxylic acid bisimides (PBIs) with terminally linked polyglycerol dendrons of four different generations have been synthesized. These PBI dyes reveal a strong dendritic effect, enabling outstanding fluorescence quantum yields in water up to almost 100% for the highest dendron generation.
dyes, new amphiphilic molecules are needed. In this paper we describe a new class of triblockamphiphiles that we have synthesized by a straightforward convergent approach. These amphiphiles each consist of a nonpolar biphenyl core and a polar shell based on various generations of monoaminopolyglyceroldendrons, coupled to the core through amide linkages (1). For the synthesis of these monoamino dendrons
