Tribenzotriquinacene Fused Dimers ("Fusodimers")-Synthesis and Host-Guest Properties. [PDF]
ChemistryTwo tribenzotriquinacene units merged with each other in either syn‐ or anti‐orientation of the bowls have become accessible in a short synthesis. In contrast to the anti‐isomer, the syn‐isomer forms 1:1 host–guest complexes with both C60 and C70 in solution and in the solid state, as shown by 1H NMR spectroscopy and x‐ray diffraction.

Higher Fullerenes: Structure and Properties
, 1994 The structures of higher fullerenes are described based on 13C NMR measurements of isolated and purified samples. The most interesting aspect deduced from the present structural work on the higher fullerenes up to C90 is that among 19 kinds of fullerenes

Purification of small bandgap fullerenes
, 1997 A process for purification of the previously insoluble empty fullerenes and endohedral metallofullerenes was developed, based on sublimation from the soot and subsequent solubilization by electrochemical reduction.

Chemistry – A European Journal, EarlyView.Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...

Benzylic Oxidation of Pillar[5]Arene: From Homo‐ to Cross‐Conjugated Macrocyclic Systems
Chemistry – A European Journal, EarlyView.Selective benzylic oxidations of pillar[5]arene have been carried out to generate all the possible oxidized derivatives containing from one up to five carbonyl subunits. Effects resulting from the homo‐ and the cross‐conjugation within this series of compounds have been investigated in details and analyzed with the help of DFT calculations.

Chemistry – A European Journal, EarlyView.Three new polycyclic aromatic compounds consisting of one or two five‐membered rings were synthesized by Scholl reaction or Pd‐catalyzed cyclization from fused anthracene derivatives. X‐ray analysis and DFT calculations revealed that these compounds have slightly twisted or curved structures.

Chemistry – A European Journal, EarlyView.Chiral cycloparaarylenes (CPAs) incorporating binaphthyl units were synthesized. The methoxy‐substituted and methylenedioxy‐bridged systems adopt D3‐ and C3/C1‐symmetric structures, respectively. They exhibited distinct solid‐state emission and aggregation‐induced emission enhancement (AIEE).
