Synthesis, Photophysical Properties, and Nanocrystal Formation of a New Class of Tetra‐N‐Substituted Perylenes

Multiple aggregates from multiple polymorphs: structural and mechanistic insight into organic dye aggregates

“…Organic particles which exhibit nanocrystalline order potentially overcome this problem by exploiting X-ray diffraction, 44–47 however, nanocrystals constitute a small percentage of the thousands of reported organic aggregates formed from solution. 48–55…”

Ditopic N-Heterocyclic Pincer Carbene Complexes Containing a Perylene Backbone

“…3,4,9,10-Tetraaminoperylene (TAP), which was first reported in 1919 by Zinke and Unterkreuter, , consists of two diaminonaphthalene units linked to each other through the peri position. In recent years, we developed an efficient synthetic route to TAP derivatives, , which were shown to bind inter alia to boron and aluminum via the nitrogen atoms, forming highly fluorescent derivatives . Herein, we report the synthesis of ditopic PCP pincer ligands in which the metal-binding sites are connected via a central 3,4,9,10-tetraaminoperylene-derived fluorophore, their coordination chemistry with rhodium, and the influence of the metal coordination on their photophysical properties.…”

A novel perylene diimide-based tetrahedral molecule: Synthesis, characterization and self-assembly with gold nanoparticles

“…[6][7][8] They are highly absorbing in the visible to near-IR region (ε ≈ 10 5 M -1 cm -1 ) and emit fluorescene with quantum yields near unity. 9,10 Perylene based chromophoric arrays 11,12 are promising components for the construction of optical and electronic molecular devices. 13,14 The ability to assemble nanoparticles with controllable size and shape [15][16][17][18][19][20][21] is of great interest, due to their potential applications in sensors, [22][23][24][25][26] catalysts 27,28 and optoelectronic nanodevices.…”
