A charge-transfer (CT) complex was formed between corannulene (C20H10) and lithium ion-encapsulated [60]fullerene (Li(+)@C60) with the binding constant KG = 1.9 × 10 M(-1) by concave-convex π-π CT interactions in benzonitrile at 298 K, exhibiting a broad CT absorption extended to the NIR region. Femotosecond laser excitation of the C20H10/Li(+)@C60 CT(More)
There are few reports on pulmonary metastasis from cholangiocarcinoma; therefore, its incidence, resectability, and survival are unclear. Patients who underwent surgical resection for cholangiocarcinoma, including intrahepatic, perihilar, and distal cholangiocarcinoma were retrospectively reviewed, and this study focused on patients with pulmonary(More)
Most common macrocycles such as crown ethers, porphyrins, and macrocyclic polyamines show versatile, excellent functions in a variety of research fields such as coordination chemistry, supramolecular chemistry, analytical chemistry, and material sciences. Thus, the rational design of a new class of readily synthesized macrocyclic metal ligands is a key to(More)
Surgical resection is the only curative treatment for biliary tract cancer (BTC); however, the recurrence rate remains high even after curative resection. There are limited data regarding the effectiveness of surgical resection for recurrent BTC. We report the favorable survival outcome of a patient who underwent a hepatopancreatoduodenectomy for local(More)

Macrocyclic compounds that can bind cationic species efficiently and selectively with their cyclic cavities have great potential as excellent chemosensors for metal ions. Recently, we have developed a tetraoxime-type tetraazamacrocyclic ligand 1 formed through a facile one-pot cyclization reaction. Aiming to explore and bring out the potential of the(More)
Benzene was hydroxylated with hydrogen peroxide (H2O2) in the presence of catalytic amounts of copper complexes in acetone to yield phenol at 298 K. At higher temperature, phenol was further hydroxylated with H2O2 by catalysis of copper complexes to yield p-benzoquinone. The kinetic study revealed that the rate was proportional to concentrations of benzene(More)
The syntheses and properties of corannulenes carrying electron-withdrawing groups (F, CF3 , C6 F5 ) are reported. Direct fluorination of corannulene (C20 H10 ) was carried out with xenon difluoride, and the crystal structure of the product was confirmed by the X-ray analysis. Novel trifluoromethylated corannulenes, including the versatile(More)
Unique heterogeneous catalase-like activity was observed for metallosupramolecular ionic crystals [AuI4CoIII2(dppe)2(d-pen)4]X n ([1]X n ; dppe = 1,2-bis(diphenylphosphino)ethane; d-pen = d-penicillaminate; X n = (Cl-)2, (ClO4-)2, (NO3-)2 or SO42-) consisting of AuI4CoIII2 complex cations, [1]2+, and inorganic anions, X- or X2-. Treatment of the ionic(More)
