Homochiral BINOL-based macrocycles with π-electron-rich, electron-withdrawing or extended spacing units as receptors for C60

The "one-pot" synthesis of several homochiral macrocycles has been achieved by using π-electron-rich, electron-deficient or extended aromatic dicarboxylic acids in combination with an axially-chiral dibenzylic alcohol, derived from enantiomerically-pure BINOL. Two series of cyclic adducts with average molecular D 2 and D 3 molecular symmetries, respectively, have been isolated in pure forms. Th...

Redox rich dicobalt macrocycles as templates for multi-electron transformationsw

The reversible transformation of substrates by several electron equivalents is a key goal of chemical energy storage. Toward this aim, extensive effort has been devoted to study catalysts that mediate the multi-electron reduction of substrates including protons, CO2 and N2. 2 In order to achieve such transformations with minimal energy input, catalysts that operate at low overpotentials are des...

Redox rich dicobalt macrocycles as templates for multi-electron transformations.

Pyridazine-templated dicobalt macrocycles reversibly support five oxidation states with unusually positive Co(II)/Co(I) redox couples, and are also active proton reduction electrocatalysts.

Yellow NIR dye: π-fused bisbenzoBODIPYs with electron-withdrawing groups.

Bicyclo[2.2.2]octadiene-fused (BCOD-fused) bis(benzoborondipyrromethene)s (bisbenzoBODIPYs) bearing electron-withdrawing groups such as fluorine and cyano groups were prepared either by incorporating tetrafluoroisoindole moieties into BODIPY chromophores or by introducing cyano or ethoxycarbonyl groups at the 3,5-positions. The BCOD-fused bisbenzoBODIPYs were quantitatively converted to the cor...
