Homoazulene

Preparation and luminescence properties of Tb3+ doped ZrO2 and BaZrO3 phosphors

“…However, in the present investigation Raman spectra of sample heated to 700 1C showed five broad peaks at about 228, 275, 471, 478 and 639 cm À 1 , which confirm the presence of predominantly tetragonal phase in the combustion-synthesized ZrO 2 powder, and the Raman spectra of the sample heated to 1000 1C showed twelve sharp and well defined peaks, which confirms the presence of monoclinic phase in addition to cubic-tetragonal phases [23,24]. It is well known that the tetragonal phase can be dramatically stabilized by the addition of solutes such as MgO, Y 2 O 3 , CaO, etc [25]. Tb 2 O 3 may also be considered as another phase stabilizer for the zirconia.…”

“…And it is well known the t-phase can be dramatically stabilized by the addition of solutes such as MgO, Y 2 O 3 , CaO, etc. [7]. It is considered that Tb 2 O 3 is another phase stabilizer for the zirconia.…”

Facets of the Tetsuo Nozoe Legacy Immortalized in an Enduring Series of International Symposia on Novel Aromatic Compounds (ISNA)

“…My students and I did go on to complete our synthesis of homoazulene (6), [32,33] and we studied its chemistry for several years. Masamune had already demonstrated the "aromaticity" of the hydrocarbon by NMR spectroscopy, [34] and we went on to show that the compound even undergoes normal electrophilic aromatic substitution.…”
