Azophenol dyes 1–5 having the permethylated cyclodextrin and/or crown moieties have been synthesized. Compounds 1 and 2 provide critical information for discrimination among 1°–3° amines by unique color changes. Addition of 1° and 2° amines to solutions of 1 or 2 in chloroform shifts the absorbance maximum of the initial solutions from 380nm to ∼580nm and ∼530nm, respectively, but no change is observed...
Three long chain alanine-based amphiphiles (1–3) possessing either a saturated long alkyl chain group or unsaturated groups as the self-assembling unit of a highly organized molecular architecture were synthesized. Their self-assembling properties were investigated using EF-TEM, SEM, CD, XRD, and FTIR. The d-form (1) and the l-form (2) enantiomers showed the opposite CD signals. Furthermore, electron...
