The engineered 19F MRI probes achieved unprecedented ratiometric ΔδF variations of up to 13 ppm, enhancing sensitivity significantly.
Positional-isomerism was critical in amplifying ΔδF from 1 to 13 ppm, enabling precise control over response magnitude.
Strategies like spiro-isomerism and positional-isomerism were integrated to create a generalizable platform for 19F MRI.
The designed probes allow for direct visualization of pH gradients, yielding sharp, interference-free images for biological applications.
