three. Since the two constrained derivatives cannot twist about the amino group, they must emit from a planar intramolecular charge-transfer excitedstate. The similar photophysical behavior suggests that dansyl also emits from a PICT excitedstate instead of a twisted intramolecular charge transfer state.

molecules such as dyes. This modification is usually performed as a final step, since sulfonated molecules are poorly soluble in most organic solvents, which complicates their synthesis and purification. This work compares the intrinsic lability of different sulfonate esters, identifying newsulfonateprotectinggroups and mild, selective cleavage conditions.
