L-threoninol as a chiral linker of azobenzene for the effective photo-regulation of DNA tripler formation
An azobenzene was enantioselectively attached to the 5'-end of oligo(T) through D- or L-threoninol. Photo-isomerization of azobenzene, tethered on L-threoninol, induced much larger change of melting temperature of tripler formation than did that on the D-form.
