Abstract:The
metal-mediated dimerization of oligoquinoline foldamers
terminated
at one end with an oligo(phenylenevinylene) and at the other with
a carboxylic acid (OPV-Q
n
A, where n = 4, 8, 17, and 33), and the complexation of OPV-Q8A and Q16A was promoted in chloroform by the addition
of a concentrated 16 M aqueous sodium hydroxide solution. UV–vis
absorption and time-resolved fluorescence anisotropy (TRFA) experiments
were conducted to determine, respectively, the concentration and the
average rotational time ⟨ϕ⟩ o… Show more
