Photophysical and photochemical properties of corannulenes studied by emission and optoacoustic measurements, laser flash photolysis and pulse radiolysis

Synthesis of Pyrrole‐Fused Corannulenes: 1,3‐Dipolar Cycloaddition of Azomethine Ylides to Corannulene

“…490 nm; 7:c a. 540 nm) and absorption spectra were virtually inert to the polarity of solvents.T he observed absorption wavelengths are bathochromically shifted relative to those of 1 [37] and similar to those of related molecules bearing an ullazine structure. [26,27] TheHOMO and LUMO energies of 6 and 7 were estimated by combining the results of UV absorption analysis and the oxidation potentials of 6 and 7 measured by cyclic voltammetry (see Figure S14 and Table S4).…”

Molecular curvature tradeoffs: Bending a planar trimercury unit over bowl-shaped polyaromatic hydrocarbons

“…Non-planar aromatic hydrocarbons emit light upon exposure to photons and are thus photoluminescent [23,27,28]. A solid sample of corannulene shows strong blue luminescence at room temperature with l max ¼ 454 nm (l exc ¼ 350 nm) [22].…”

Buckybowls: Corannulene and Its Derivatives

“…The properties of corannulene have been known to be modified by fusing with a variety of substituted groups with different compositions, lengths and numbers, by introducing additional five‐ and/or six‐membered rings, by forming salt‐like complexes with various metals and metal‐containing complexes and by working as a host of inclusion complexes, as explained above. Buckybowls, representing by corannulene and its derivatives, have been discussed and reviewed as possible candidates for different applications, such as molecular switches and motors for future nanoscale machinary, specifically important members in organometallics and supramolecules for chemical encapsulation and delivery of drugs and biomolecules, photoemitters of electrons, etc., as well as the precursors for the synthesis of fullerenes and redox‐acitive materials …”
