Facile Synthetic Route to Highly Luminescent Sila[7]helicene
Hiromi Oyama,Koji Nakano,Takunori Harada,Reiko Kuroda,Masanobu Naito,Kazuyuki Nobusawa,Kyoko Nozaki +6 more
TL;DR: A facile synthetic route to dimethylsila[7]helicene by using a Lewis acid catalyzed double-cyclization reaction for construction of the twisted two phenanthrene moieties is described.
Journal ArticleDOI
λ5‐Phospha[7]helicenes: Synthesis, Properties, and Columnar Aggregation with One‐Way Chirality
TL;DR: It is hypothesized that the use of dipole–dipole interactions in addition to inherent p–p stacking interactions might produce a one-dimensional columnar arrangement of helicenes, and the preparation of l-phospha[7]helicenes 1 and 2 are reported as a new family of helicalenes.
Journal ArticleDOI
Synthesis and Properties of [7]Helicene-like Compounds Fused with a Fluorene Unit.
TL;DR: Helicene-like compounds with a fluorene unit were successfully synthesized using a platinum-catalyzed double cyclization reaction and were found to exhibit a high fluorescence quantum yield and a relatively large g value of circularly polarized luminescence (CPL) for small molecules.
Journal ArticleDOI
1-Aryl-4-silylmethyl[60]fullerenes: synthesis, properties, and photovoltaic performance.
Yutaka Matsuo,Hiromi Oyama,Iwao Soga,Iwao Soga,Toshihiro Okamoto,Toshihiro Okamoto,Hideyuki Tanaka,Akinori Saeki,Shu Seki,Eiichi Nakamura +9 more
TL;DR: The efficient nucleophilic addition of aryl Grignard reagents to C(60) in the presence of DMSO produced 1,2-arylhydro[60]fullerenes after acid treatment, which yielded the target compounds, 1-aryl-4-silylmethyl[60]:4-MeOC(6)H(4), thienyl.
Journal ArticleDOI
Ring-opening reaction of tetrahydrofuran on the penta(organo)[60]fullerenes: synthesis of hydroxybutyl, methacrylate, and norbornene derivatives
TL;DR: In this article, the ring-opening reaction of tetrahydrofuran on penta(methyl)- and penta n -butylphenyl[60]fullerenes in the presence of chlorotrimethylsilane giving penta (organo)fullerene hydroxybutyl derivatives, C 60 R 5 (C 4 H 8 OH) (R = Me, n BuC 6 H 4 ).
