Definition of Schiff base in English: Schiff basenoun Chemistry An organic compound having the structure R¹R²CNR³ (where R¹,²,³ are alkyl groups and R¹ may be hydrogen). Example sentencesExamples - The chloride is close to the Schiff base, although in unfavorable position for hydrogen bonding.
- In some crystal structures, the conformational changes are limited to local residues surrounding the Schiff base.
- On the other hand, in polar conjugated systems such as protonated Schiff bases the funnel shows a structure with just one twisted double bond.
- Thus, continuous illumination creates another kind of deprotonated Schiff base containing photoproduct unrelated to the azide photocycle we described here.
- This reorientation of the Schiff base determines the vectoriality of the proton pump.
Origin Late 19th century: named after Hugo Schiff (1834–1915), German chemist. |
