Characteristics of Hydroxynaphthalimide Trifluoromethanesulfonate Photoacid Agent

Acid Production Mechanism: Upon exposure to a suitable light source, the sulfonate ester bond breaks, leading to acid generation. Photoacid generators based on naphthalene imide sulfonate esters exhibit enhanced acid production efficiency, with some naphthalene-structured photoacids being twice as potent as others.

 

 

 

Characteristics of Naphthalimide Acid Generators:

 

High light absorption energy; excellent solubility in organic solvents; robust thermal stability; rapid acid production rate.

 

Easy to enhance the properties of the corresponding photoacid by chemically modifying and tailoring the structure. Naphthalene imide naphthalene sulfonate photoacids can be finely tuned through various chemical modifications and tailoring, making them suitable for adjusting solubility, polyaromaticity, or altering the substitution pattern of the naphthalene core. These attributes render them suitable for multifunctional photoinitiation applications.
