Publikováno v: Tetrahedron Letters. 54:4380-4384
The fluorescence (FL) and structural properties of dibenzoylmethanatoboron difluoride (1aBF2) and its diisopropyl derivative (1bBF2) in the crystalline state were investigated. Both 1aBF2 and 1bBF2 in their crystalline states have FL spectra that con

Remarkable Solvatofluorochromism of a [2.2]Paracyclophane-Containing Organoboron Complex: A Large Stokes Shift Promoted by Excited State Intramolecular Charge Transfer
Autor: Atsushi Sakai, Mirai Tanaka, Hiroshi Ikeda, Yuichi Yoshimoto, Takuya Ogaki, Kazuhiko Mizuno, Eisuke Ohta, Shunsuke Muraoka, Yasunori Matsui
Publikováno v: ChemPhotoChem. 1:135-135
An organoboron complex containing a [2.2]paracyclophanyl group (2BF₂) exhibits remarkable solvatofluorochromism associated with a large Stokes shift. With increasing the solvent polarity, the fluorescence (FL) color of 2BF₂ changes from sky blue

3,14-Bis(p-nitrophenyl)-17,17-dipentyltetrabenzo[a,c,g,i]-fluorene: a new fluorophore displaying both remarkable solvatochromism and crystalline-induced emission
Autor: Yoshiaki Ueda, Kazuhiko Mizuno, Mirai Tanaka, Chitoshi Kitamura, Hiroshi Ikeda, Yuichi Yoshimoto, Takeshi Kawase, Hiroyuki Kurata, Yusuke Tanigawa
Publikováno v: Chemistry, an Asian journal. 8(2)
A series of 17,17-dialkyl-3,14-diaryltetrabenzofluorenes were efficiently prepared by using Suzuki-Miyaura cross-coupling reactions of the corresponding 3,14-dibromo derivatives. Studies of the unique fluorescence properties of these compounds showed
