A unimolecular hydrogen-bonded network is formed by a perylene-diimide derivative following surface self-assembly leading to the formation of pores of appropriate dimensions to accommodate regularly spaced guest C(60) molecules.

The fluorescence sensing of amine vapor was largely enhanced upon using ultrathin nanofibers, which were fabricated from N-(1-hexylheptyl)perylene-3,4,9,10-tetracarboxyl-3,4-anhydride-9,10-imide by a new self-assembly approach.

A simple and unique strategy has been successfully designed for sensitive detection and rapid clearance of bacterial lipopolysaccharides (LPS) by integration of core-shell Fe3O4@SiO2 magnetic nanoparticles with a perylene-diimide (PDI) conjugated LPS-recognition peptide.

Mixtures of an amphiphilic perylene bisimide derivative and tetramethoxysilane in the absence of solvents have been found to exhibit stable columnar liquid-crystalline phases which transform into macroscopically oriented nanoporous silica films as a result of simple mechanical shearing.

Polyhedral oligomeric silsesquioxane (POSS)-containing red fluorescent nanoparticles were designed and prepared for rapid detection of aqueous fluoride ions by virtue of the fluoride-triggered self-quenching of perylene bisimide dyes in nanoparticle cores.

Conventional photoredox catalytic additions of alcohols to olefins require additives, like thiophenol, promote back electron transfer. The concept “photozymes” assumes that forward and backward transfer steps in a cycle are controllable by substrate binding photocatalytically active peptides. Accordingly, we synthesized short tripeptide modified with 1,7-dicyano-perylene-3,4 : 9,10-tetracarboxy...

This review provides an update on advances in the area of electrical mode sensors using organic small molecule n-type semiconductors based perylene. Among molecules, perylene diimides (PDIs) are important class materials due to their outstanding thermal, chemical, electronic, and optical properties, all which make them promising candidates for a wide range electronic devices including sensors, ...

Symmetry breaking caused by geometric fluctuations can enable processes that are otherwise forbidden. An example is a perylene bisimide dyad whose dipole moments are perpendicular to each other. Förster-type energy transfer is thus forbidden at the equilibrium geometry since the dipolar coupling vanishes. Yet, fluctuations of the geometric arrangement have been shown to induce finite energy tra...

The indirect electroreductive coupling of aryl halides and pyrroles was successfully conducted using a catalytic amount of perylene bisimide as a mediator in 1-ethyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)imide ([EMIM]NTf2)/DMSO.
