Stimulus-responsive materials with designable integrated functions bridge
the intelligent systems in future lifestyles with the Internet of Things (IoT).
The growing trend for IoT and corresponding advanced devices will involve
a great number of electronic disposables, which may place heavy burdens
on the environment. Here, an elaborately designed multistage responsive
material is reported for real-time, reversible light-writing based on organized
stage-by-stage responsive behaviors and polarity-dependent physicochemical
fluorescence response, where the stimulus is accurately delivered through
a completely reversible “light-heat-fluorescence” pathway. The resulted
materials can be pollution-freely written by hand-controlled near-infrared laser
within 5 s, spontaneously erased within 20 s, and exhibit excellent re-writing
ability (more than 5000 times while the variance of chromaticity coordinates
<0.0008), which is difficult to achieve by traditional laser writing technologies.
This study is a step toward high-performance long-life functional devices
based on reversible multistage responsive materials for future IoT lifestyles.
