| 英文摘要 | The mimicry of some elementary functions of neurons and electronic computers at the molecular scale has been attracting more and more interest, which has strongly pushed chemists to explore digital logic function and circuits at the molecular level for the purpose of molecular computing and biocomputer. As molecular switches convert input stimulations into output signals, the principles of binary Boolean logic can be applied to the signal transduction operated by molecules under appropriate conditions. Implementation of the most common Boolean functions (PASS, YES, NOT, AND, NAND, OR, NOR, XOR, XNOR, and INH) with chemical systems is possible now. Holding these basic logic functions in hands, the chemists are devoting to novel computational architectures of complicated functions, as well information security in the molecular platform, to create a molecular analogue for every electronic product. A molecular 2:1 multiplexer comprises two photochromic moieties, dihydropyrene and dihydroindolizine units, linked to a central porphyrin to perform as a combinational circuit to connect any one of several possible inputs to an output. Molecular sequential logic requires the control of the kinetic behavior of the chemical system. A molecular keypad lock and crossword puzzles and logic memory are capable based on a molecular species in solution whose fluorescence is switched on only in response to a correct sequence of input signals, which are reminiscent of electronic keypad locks, a common security device that can control the opening of a door or a safe. An approach to the assembly of the biomolecular keypad lock using the enzyme-based networking system is also realized. Further, a molecular computing platform in defending against information risk is constructed, where chemical-encoded user identity information can be transmitted from sequential logic unit to combinational logic circuit, and hence resulting in the user-specific digital functionalities. |
