Near-infrared(NIR) fluorescent emission can realize very small photodamage to biological samples,minimum interference from biomolecule autofluorescence,and deep tissue penetration.
A multiple-responsive water-soluble [3]pseudorotaxane was constructed by water-soluble pillar[5]arene-based molecular recognition and disulfide bond connection.
In the present study,we report the synthesis of short-chain C12-sphinganine and a small library of its 1,2,3-triazoles from commercially available and inexpensive 10-undecenoic acid as a starting mate
