“…Recently, electrofluorochromism at the single‐molecule level was achieved based on inelastic tunneling of electrons between a scanning transmission electron microscope (STEM) tip and a gold electrode . Nondestructive fluorescence memory may also be created using electrofluorochromism because electrochemical inputs are orthogonal to fluorescence processes, thereby enabling reversible write–read–erase memory cycles …”

Although electrofluorochromism enables unique optoelectronic applications, its utility has been limited by poor reversibility. It is demonstrated that high reversibility in electrofluorochromism is obtainable from molecular dyads having a redox‐stable acceptor and an aromatic or antiaromatic donor. The structural control aims to generate excited‐state conjugation that produces twisted intramolecular charge‐transfer fluorescence, while suppressing the ground‐state conjugation in order to confine electrochemical processes exclusively within the acceptor unit. Overpotential‐free electrofluorochromism can be achieved with a high fatigue resistance against repeated electrochemical cycles. The electrofluorochromism is investigated using structural, spectroscopic, electrochemical, spectroelectrochemical, and quantum chemical techniques. The studies reveal that electrochemical gating of intramolecular charge transfer is the key mechanism underlying the improved electrofluorochromism performance. The study will provide novel insights into the future development and applications of electrofluorochromic devices.

“…Private information encryption is the symbol of the times and the only way to update and develop secure information sharing. To protect a user's security, it is necessary to encrypt and protect sensitive personal information (SPI), as shown in [1,2]. Currently, users are becoming more concerned with the privacy of their information as opposed to just the novelty of the application being used [3].…”

The new developments in smart cyber-physical systems can be shown to include smart cities, Internet of things (IoT), and for the most part smart anything. To improve the security of sensitive personal information (SPI) in cyber-physical systems, we present some novel ideas related to the encryption of SPI. Currently, there are issues in traditional encryption methods, such as low speed of information acquisition, low recognition rate, low utilization rate of effective information resources, and high delay of information query. To address these issues, we propose a novel efficient encryption algorithm for the security of incremental SPI. First, our proposed method analyzes user information resources and determines valid data to be encrypted. Next, it uses adaptive acquisition methods to collect information, and uses our encryption method to complete secure encryption of SPI according to the acquisition results. Our experimental analysis clearly shows that the algorithm effectively improves the speed of information acquisition as well as effective information recognition rate, thus enhancing the security of SPI. The encryption model in turn can provide a strong guarantee for user information security.
