Amphiphiles are widely explored for the solubilization of various hydrophobic molecules especially drugs in water. Recently, aromatic amphiphiles emerged as a new class organic semiconductors However, synthesis these systems involves several steps and often requires use expensive metal catalysts. Here we describe design type flexible amphiphilic trication (FAT) its application FAT has been synt...

The isomerism effect on the aggregate emission properties of perylene diimide derivatives is studied. Banking their bright emission, a cellular imaging test based nanoparticles also conducted.

A n-type low bandgap conjugated polymer based on perylene diimide and cyclopenta[2,1-b:3,4-b']dithiophene, which exhibits excellent reversible electrochemical properties in both n-doping/dedoping and p-doping/dedoping processes, was designed, synthesized and characterized.

N-type cascade electron transfer was achieved for the first time along an oxidative gradient in the triad of ferrocene-perylene tetracarboxylic bisimide-[60]fullerene, providing a promising new strategy of supramolecular architecture for solar energy conversion.

We have synthesized two alkenyl (C-6 and C-11 chains) pyrenes and one alkenyl (C-11 chain) perylene as the σ-π systems, which were electro-grafted on H-terminated Si surfaces to form the respective monolayers. The I-V characteristics of the monolayers revealed pronounced rectification in forward bias with a maximum rectification ratio (RR) of 2.5 × 10(5) at 2.5 V for the C-6-pyrene 4b, 1000 at ...

The synthesis and characterisation of a novel coumarin donor-perylene bisimide acceptor light-harvesting system is reported, in which an energy-transfer efficiency of >99% is achieved. Comparison of the excited-state properties of the donor-acceptor system with model compounds revealed that although the photophysical properties of the perylene bisimide acceptor unit are affected considerably by...

We present here a new type of photoresponsive, reversible low molecular weight gel. All previous examples rely on a photoisomerisation, ring-closing or dimerization. We show that photoreduction of a perylene bisimide gelator results in the formation of a stable radical anion. The formation of the radical anion results in a change in the packing of the perylene bisimides in the self-assembled ag...

The non-covalent functionalisation of graphene is an attractive strategy to alter the surface chemistry of graphene without damaging its superior electrical and mechanical properties. Using the facile method of aqueous-phase functionalisation on large-scale CVD-grown graphene, we investigated the formation of different packing densities in self-assembled monolayers (SAMs) of perylene bisimide d...

A novel synthesis is presented of a fourfold ethynyl-substituted perylene diimide dye 4, which acts as a core molecule for the buildup of polyphenylene dendrimers. Around the luminescent core 4, a first-generation (5), a second-generation (6), and a third-generation (7) polyphenylene dendritic environment consisting of pentaphenylbenzene building blocks are constructed. The dendrimers 5 and 6 a...
