Nonlinear organic reactions to proliferate acidic and basic molecules and their applications

Area of Science:

• Organic Chemistry
• Materials Science
• Polymer Chemistry

Background:

• Acid amplifiers based on sulfonates can undergo autocatalytic decomposition.
• This decomposition generates sulfonic acids, which further catalyze the process exponentially.
• Carbamates can function as base amplifiers through a similar autocatalytic fragmentation mechanism.

Purpose of the Study:

• To present five types of acid amplifiers exhibiting acid proliferation reactions.
• To explore the application of acid and base amplifiers in photofunctional materials.
• To discuss the practical use of acid proliferation reactions in polymer films.

Main Methods:

• Investigation of sulfonate-based acid amplifier decomposition pathways.
• Synthesis and characterization of novel acid amplifier compounds.
• Integration of acid/base amplifiers with photoacid/photobase generators for material applications.

Main Results:

• Demonstration of exponential acid liberation from specific sulfonate structures.
• Identification of carbamate-based base amplifiers with autocatalytic properties.
• Successful application of amplifier systems in photolithography and polymer film development.

Conclusions:

• Acid and base amplifiers offer a powerful mechanism for signal amplification in chemical systems.
• These amplifiers have significant potential in advanced photofunctional materials, particularly photoresists.
• The controlled proliferation of acids and bases opens new avenues for polymer film modification and processing.
