Oxadisilole fused pentacenequinones and heptacenequinones
摘要:
Stable, organic solvent soluble bis- and tetrakis-oxadisilole fused pentacenequinones (5a - b) and heptacenequinones (11a - b) were synthesized. Double Diels - Alder and fourfold aldol-condensation approaches were used. Absorption, emission and fluorescence quantum yield of the previously unknown acenequinones 5a and 11a were characterized. The role of the oxadisilole substituent on the photophysical properties was addressed. (c) 2007 Elsevier Ltd. All rights reserved.
Oxadisilole-Fused Isobenzofurans. Synthesis and Characterization of Oxadisilole-Substituted Acenes
摘要:
Mono- and bis-oxadisilole-fused isobenzofurans were first synthesized and isolated. A series of mono-, bis-, and tris-oxadisilole-substituted acenes were then synthesized by benzyne Diels-Alder reactions with the isobenzofurans. The photophysical, redox, and thermal properties of these new acenes were characterized.
