About

Eri Hatano is a leading figure in the field of photochromic materials, with a research focus that elegantly bridges synthetic chemistry and biomimetic surface engineering. Her most celebrated work, "Photochromic Crystalline Systems Mimicking Bio‐Functions" (2018, 44 citations), introduces a groundbreaking approach to creating photoresponsive crystalline systems using diarylethenes. Hatano’s key contribution lies in demonstrating that upon UV irradiation, the closed-ring isomers of these photochromes can self-aggregate into needle-shaped crystals on a surface, spontaneously generating a rough, superhydrophobic texture. This innovation directly mimics natural bio-functions, such as the self-cleaning properties of lotus leaves, but with the added advantage of optical control. By harnessing light to trigger both a chemical and a physical transformation, Hatano has opened new avenues for smart surfaces, adaptive coatings, and micro-actuators. Her work is highly cited for its conceptual elegance and practical potential, establishing her as a pioneer in the emerging field of photo-induced crystalline morphing. For students and researchers, Hatano’s research exemplifies how fundamental photochemistry can be translated into dynamic, bio-inspired materials.
