LainéJournal of the American Chemical Society2010 132 (46), 16700-16713The multifaceted potentialities of expanded pyridiniums (EPs), based on one pyridinium core bearing a 4-pyridyl or 4-pyridylium as the N-pyridinio group, are established at both experimental and theoretical levels. Two classes of head-to-tail (htt) EPs ...

Synthesis of Triarylmethane and Xanthene Dyes Using Electrophilic Aromatic Substitution Reactions
James V. McCullagh and Kelly A. DaggettJournal of Chemical Education2007 84 (11), 1799Synthesis of Triarylmethane and Xanthene Dyes Using Electrophilic Aromatic Substitution Reactions
James V. McCullagh and Kelly A. DaggettJournal of Chemical Education2007 84 (11), 1799The synthesis of dyes has long been a popular topic in organic chemistry laboratory experiments because it allows students to see first hand that reactions learned in class can be used to make compounds with useful applications. In this experiment ...

Tethering of Modified Reichardt's Dye on SBA-15 Mesoporous Silica: The Effect of the Linker Flexibility
Sonia Fiorilli, Barbara Onida, Claudia Barolo, Guido Viscardi, Daniel Brunel, and Edoardo GarroneLangmuir2007 23 (4), 2261-2268Tethering of Modified Reichardt's Dye on SBA-15 Mesoporous Silica: The Effect of the Linker Flexibility
Sonia Fiorilli, Barbara Onida, Claudia Barolo, Guido Viscardi, Daniel Brunel, and Edoardo GarroneLangmuir2007 23 (4), 2261-2268Solvatochromic Reichardt's dye has been covalently anchored to both aniline-functionalized and propylamine-functionalized SBA-15 mesoporous silicas. The former offers a rigid linker to the surface; the latter offers a flexible one. The optical properties ...

A Convenient Method for Synthesizing Modified 4-Nitrophenols

Yumi Nakaike, Yoshio Kamijo, Satoshi Mori, Mina Tamura, Nagatoshi Nishiwaki, and Masahiro ArigaThe Journal of Organic Chemistry2005 70 (24), 10169-10171β-Nitroenamine having a formyl group behaves as the synthetic equivalent of unstable nitromalonaldehyde upon treatment with ketones under basic conditions and leads to 2,6-disubstituted 4-nitrophenols. The present method is safer than the conventional one ...

Counterion-Induced Transformations of Cationic Surfactant Micelles Studied by Using the Displacing Effect of Solvatochromic Pyridinium N-Phenolate Betaine Dyes
