Ink-free printing based on rewritable paper is an efficient and environmental friendly way to reuse paper, protect resources, and save energy for sustainable development of human society. Among various kinds of rewritable media, light responsive rewritable paper (LRP) is one of the most popular research areas due to its clean and favorable noncontact writing. Visible light is more suitable for LRP for its superior penetration and much less damages to organic molecules than UV light. However, visible-light-responsive rewritable paper (VLRP) has only limited successes so far. Herein, a VLRP is newly designed and fabricated based on photoinduced proton transfer (PPT) between photoacid and pH-sensitive dyes. Success of it is highly benefited from systematical investigation and in-depth understanding on the key influence factors, such as concentration-induced undesired isomerization, temperature, humidity, and light intensity, on the PPT and its inverse process. As-prepared VLRP shows long-awaited properties, such as, high color contrast and resolution, appropriate legible time of prints, excellent reversibility (>100 cycles), easiness to achieve multicolor prints, and agreeing well with environmental concept of green printing. In addition, study of influence factors on PPT in this work, to some extent, may also help people understand complex photocycle process in biosystem. A new kind of visible-light-responsive rewritable paper (VLRP) is designed and fabricated based on bioinspired photocycle from photoinduced proton transfer (PPT) between a photoacid and a proton receptor dye. Systematical investigation and in-depth understanding key influence factors on the PPT and its inverse process endow the VLRP with excellent performances.
