Introduction As global environmental problems become increasingly serious, the effective use of green energy becomes particularly critical [1], [2], [3]. However, the intermittency and instability of green energy limited its direct application. Exploring various energy storage devices that can store green power to stabilize its output is critical.

“Photochromism” is defined as the reversible color change induced by light irradiation. More specifically, it refers to the reversible transformation that occurs in a chemical substance between two forms due to electromagnetic radiation. Photochromism is an important characteristic of functional molecular materials [1].
