Microporous polyphenylenes with tunable pore size for hydrogen storage

A series of highly porous polymers with similar BET surface areas of higher than 1000 m2 g-1 but tunable pore ranging from 0.7 nm to 0.9 nm were synthesized through facile ethynyl trimerization reaction to demonstrate the surface pro

Self-assembly of radially π-extended tetrathiafulvalene tetramers for visible and near infrared electrochromic nanofiber

The self-assembly and electrochromic nanofiber formation of radially 7pi;-extended tetrathiafulvalene (TTF) tetramers anchored to 1,2,4,5-tetraethynylbenzene were investigated. The tetramer with SBu-substituents underwent self-assembly in solution. Cationic species of the tetramer, obtained by chemical oxidation with Fe(ClO4)3, exhibited a marked electrochromism in the solution. Their electronic spectra revealed absorption bands corresponding to intermolecular mixed-valence aggregation based on (TTF//TTF)+, and π-aggregation based on (TTF?+//TTF?+) due to the strong molecular association in the cationic species. Furthermore, the tetramer formed an entangled nanoscale fibrous material from CHCl3 hexane. Electrochemical oxidation of the nanofiber on an indium tin oxide electrode revealed a repeatable redox profile. The nanofiber displayed remarkable electrochromic behavior: The color of the fiber changed from purple (neutral) to brown/brownish green (dication and trication) and green (tetracation). These color changes of the nanofiber are similar to those in solution, and the electronic spectra of the oxidized nanofibers reflected the stacked TTF units in the cationic nanofibers.

Microwave-assisted unprotected Sonogashira reaction in water for the synthesis of polysubstituted aromatic acetylene compounds

A microwave-assisted, efficient and rapid Sonogashira reaction was developed for the synthesis of polysubstituted aromatic alkynes. The reaction was made environmentally friendly and easy to perform by replacing the traditional amine solvents with water.

Modulated morphology in the self-organization of a rectangular amphiphile

The rectangular oligo(phenylene ethynylene) amphiphile 1 has been synthesized to investigate its self-assembling features in solution and onto surfaces. Concentrationdependent and variable-temperature NMR experiments firstly demonstrate the influence of t

Palladium-catalyzed cross-alkynylation of aryl bromides by sodium tetraalkynylaluminates

Sodium tetraalkynylaluminates (1-4), prepared from NaAlH4 and terminal alkynes, cross-couple with aryl bromides in the presence of Pd(0) and Pd(II) catalysts. The reactions take place in boiling THF or DME. The process is applicable to both hom
