acidinspired

Acidinspired is a design philosophy in chemistry and materials science that uses principles of acidity to guide the development of catalysts, functional materials, and responsive polymers. The approach emphasizes translating concepts such as acid strength, proton transfer, and the organization of acid sites into tangible structures that enable selective reactivity.

Core concepts include matching acid strength to the reaction step, controlling the density and accessibility of acid sites, and engineering frameworks that stabilize reactive intermediates. Practitioners employ solid acids (zeolites, sulfated oxides, acidic frameworks), immobilized organocatalysts, and polymers with tethered acid groups to create materials with defined acid topology and improved transport properties.

Applications span catalysis (dehydration, isomerization, esterification), energy-related materials (proton-conducting membranes), chemical sensing, and controlled degradation or release in polymers through acid-labile linkages.

Evaluation and challenges: achieving uniform acid sites, preventing deactivation by coking or poisoning, balancing activity with selectivity, and ensuring stability under operational conditions. Common metrics include acid-site density, Brønsted/Lewis acid ratio, turnover frequency, and lifetime.

Origin and usage: The term acidinspired is used in contemporary literature as a descriptive label for work that explicitly uses acid-chemistry principles to inform design. It is not a strictly defined subfield, but a cross-cutting motif across catalysis, materials, and polymer science.
