Description

Application

(S)-(+)-2-Butanol can be used:

To synthesize chiral asymmetric perylene diimides (PDI) that spontaneously self-assemble into one-handed nanotubes that are photoconductive or fluorescent in nature.
To synthesize bulky chiral vinyl monomers that can be radically polymerized to helical polymers with an excess screw sense.
As chiral solvent to study excited state photo transfer of the photoacid, 5,8-dicyano-2-naphthol (DCN2) in chiral environment.
