Abstract

original image

Sticky fingers: The emission intensity of modified pyrimidines containing an aryl moiety, linked by a single bond to the nucleobase in the 5-position, show a remarkable sensitivity to sample viscosity (see picture), a trait typical for chromophores bearing a molecular rotor element.
