Multichromophore perylene arrays were designed and synthesized to have extremely efficient resonance energy transfer. Using broadband ultrafast photoluminescence and transient absorption spectroscopies, transfer timescales of approximately 1 picosecond were resolved, corresponding to efficiencies of up to 99.98%. The broadband measurements also revealed spectra corresponding to incoherent trans...

A novel ruthenium(ii) water oxidation catalyst equipped with axial perylene bisimide ligands that self-assembled into nanofibers was synthesized. This fiber-embedded catalyst exhibited improved performance compared with a monomeric reference for the oxidative water splitting reaction.

Well-defined single-crystalline nanobelts with strong fluorescence were fabricated from a perylene tetracarboxylic diimide molecule modified with specific side-chains that afford flip-flap stacking, rather than the common translated stacking, between the molecules along the long axis of the nanobelt. The nanobelts thus fabricated possess highly polarized, self-waveguided emission, making them i...

A series of non-alternant aromatic dicarboximides was synthesized by manipulating the perylene bisimide framework through introduction heptagonal rings, which strongly alter their optoelectronic properties.

The orientational distribution and rotational dynamics of planar perylene molecules incorporated into spherical vesicles of palmitoyl-δ-9-oleoyl(16:0,18:1)phophatidylcholine (POPC) was studied using time-resolved fluorescence anisotropy. The experimental anisotropy decay curves were analyzed using a global target approach. Here, anisotropy curves obtained at six temperatures above the gel-lamel...

Multifunctional coatings offer many advantages towards protecting various surfaces. Here we apply aggregation induced segregation of perylene diimide (PDI) to control the surface morphology and properties of silica nanoparticles. Differentially functionalized PDI was incorporated on the surface of silica nanoparticles through Si-O-Si bonds. The absorption and emission spectra of the resultant f...
