<p>Photochromic materials offer several advantages, including high modifiability, rich color variations, and fast photoresponse. However, the matrix often imposes geometric constraints on the photoisomerization of these compounds, thereby reducing their phototoggle efficiency. Integrating photochromic molecules into a robust porous framework with precisely designed pores, such as metal–organic frameworks, covalent organic frameworks, and hydrogen-bonded organic frameworks, has emerged as a novel strategy for advancing the development of photochromic materials. This paper reviews the core principles of organic porous frameworks and their pivotal role in enhancing the performance of photochromic materials, thereby surpassing the limitations observed in solution or solid-state forms. The synergistic relationship between photochromic substances and porous frameworks is explored, and recent advancements in research on photochromic materials based on these frameworks are summarized, along with promising future directions for development.</p>
