WebJan 30, 2006 · To sum up, we have prepared a series of highly polarized dithiafulvene-containing merocyanines. As judged from their μβ values, dithiafulvenes are, in some cases, as efficient as ferrocene or dialkylaminophenyl donors. On the other hand, when very strong acceptors are used, dithiafulvenes are less efficient than dialkylaminophenyl groups ...
Remarkable effect of the dithiafulvene structures on their capacity …
WebThis review highlights the recent progress of macromolecules consisted of electron-donating dithiafulvene units. π-Conjugated polymers with the dithiafulvene derivatives, including main-chain and side-chain systems, have been studied with the aim of improving processability of the charge-transfer (CT) complexes and increasing dimensionality of … WebJun 28, 2024 · Synthesis and optimization of reaction conditions. The one-pot reaction between ethyl acetoacetate 1a, phenyl hydrazine 3a, carbon disulfide, and dimethylacetylenedicarboxylate 4a was selected as a model reaction to produce pyrazolone-1,4-dithiafulvene hybrid 5a (Table 1).At first, the reaction was carried out in the water in … good chilly morning
