One-dimensional luminescent nanoaggregates of perylene bisimides.
A new perylene bisimide dye has been synthesized which self-assembles into columnar nanoaggregates and liquid crystalline mesophases with striking photoluminescent properties.
متن کاملControlled aggregation of peptide-substituted perylene-bisimides.
Controlled aggregation of perylene bisimides in multiple modes has been achieved via symmetric substitution with peptides. Using optical probes of aggregation, the balance of hydrophobic and electrostatic forces are found to play a key role in directing self assembly and are exploited via solvent, pH, and specific extrinsic ion effects.

متن کاملLocalization/delocalization of charges in bay-linked perylene bisimides.
The copper-mediated Ullmann coupling of 1,7-dibromoperylene bisimides afforded structurally perfect singly-linked perylene bisimide (PBI) arrays, whilst the homo-coupling of 1,12-dibromoperylene bisimides gave doubly-linked and triply-linked diperylene bisimides. The interactions of three bay-linked diperylene bisimides that differed in their linkage (singly, doubly, and triply) were investigat...
متن کاملBrightly shining nanoparticles: lipophilic perylene bisimides in aqueous phase
However, the application of such dyes in aqueous solution turned out to be appreciably more difficult. Strongly hydrophilic groups such as sulfonic acid groups, polyether groups, and pyridyl substituents, basically induce water solubility of 1; however, these materials exhibit a strong tendency to aggregate in the highly hydrophilic medium. Moreover, such dyes exhibit a high aptitude for the co...
