(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.
