“…Photochromism is a result of light-induced reversible color transition of organic, inorganic, biological, and polymeric materials. [57][58][59][60][61][62][63][64][65][66][67][68][69][70] Photochromic reactions are mainly based on cis-trans isomerization, electrocyclization, redox, and light-induced proton transfer mechanisms. The change in the molecular structure before and after light irradiation causes a remarkable variation in the absorption or photoluminescence (PL) spectra.…”

“…Organicinorganic hybrid-binary photochromic systems containing visible light-induced proton releasing agents (nanomaterials, metastable state photoacids [PAH], azobenzene, and phenolsulfophthalein) and proton acceptors (acid dyes or pH indicators) can be used in visible light-excited rewritable paper (VLRP). [62][63][64][65][66][67][68][69][70] PAH is used as a proton releasing agent to make a binary system with an acid dye, such as methyl orange (MO). Figure 2A shows that trans-PAH is transformed to a ring-closed isomer (SP) under UV light and releases protons.…”

Information recording on paper has always been the most important approach to keep records of human activity and to spread civilization. With the progress of science and technology, paper with different functions should be exploited to conform to the increasing demands in various scenarios. In one aspect, traditional paper can only be used once, and using large amounts of paper causes deforestation, additional solid waste treatment, environmental pollution, and high energy consumption. Consequently, the development of rewritable paper that is environment-friendly, low cost, and can save resources is significant for green printing. In the other aspect, information leakage brings security issues, which may lead to severe consequences, such as war outbreak, economic loss, social problems, and so on. Therefore, the development of security printing has also attracted wide interests. Stimuli-responsive photofunctional materials that have reversible variations in absorption or emission in response to changes in the external environmental have a great potential for the achievement of green and security printing. To date, much progress has been made in these research areas. This paper lists different smart materials that respond to various external stimuli, such as light, water, pH, heat, and metal ions, and summarizes the recent advances towards green and security printing. Also, we discuss the current challenges and future directions in this rapidly growing research field. It is expected that this review article will stimulate and guide future studies for the advanced green and security printing.

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.
