“…Derived from these competition, the emergence of molecular logic gates, emerged to finely tune the 1 O 2 generation. Molecular logic gates, as a promising strategy,83 was rarely applied to PDT. Combining molecular logic gates with PDT, Akkaya et al84 reported a controllable and self‐reporting PDT, realized by series logic gate.…”

With singlet oxygen (1O2) as the active agent, photodynamic therapy (PDT) is a promising technique for the treatment of various tumors and cancers. But it is hampered by the poor selectivity of most traditional photosensitizers (PS). In this review, we present a summary of controllable PDT implemented by regulating singlet oxygen efficiency. Herein, various controllable PDT strategies based on different initiating conditions (such as pH, light, H2O2 and so on) have been summarized and introduced. More importantly, the action mechanisms of controllable PDT strategies, such as photoinduced electron transfer (PET), fluorescence resonance energy transfer (FRET), intramolecular charge transfer (ICT) and some physical/chemical means (e.g. captivity and release), are described as a key point in the article. This review provide a general overview of designing novel PS or strategies for effective and controllable PDT.

“…using acid/base chemistry) has been known for a long time, it was not until the demonstration of the molecular AND gate (1; see structure in Scheme 1) by de Silva and co-workers in 1993 that the behavior was interpreted in terms of Boolean logic. [1] Since then, all existing 2-input logic gates have been realized on the molecular scale, as have a large variety of more complex devices [2][3][4][5][6][7][8][9][10][11] such as adders and subtractors, [9,12,13] multiplexers/demultiplexers, [14][15][16][17] encoders/decoders, [18,19] keypad locks, [20][21][22][23][24][25][26] latches/flip-flops, [10,[27][28][29][30][31][32][33][34] and multivalued logic devices. [35,36] The initial impetus for conducting research in molecular logic has been to make molecules imitate the functions of silicon circuitry, the main objectives being miniaturization (via a bottom-up approach) and implications thereof, such as minimal power consumption.…”

Information Processing with Molecules—Quo Vadis?

2 Lead-In. Information processing at the molecular level is coming of age. Since the first molecular AND gate was proposed ca. 20 years ago, the molecular interpretation of binary logic has become vastly more sophisticated and complex. However, the field is also at a crossroads. While cleverly designed molecular building blocks are abundant, difficult questions remain. How can molecular components be flexibly assembled into larger circuits, and how can these components communicate with one another. The concept of all-photonic switching with photochromic supermolecules has shown some interesting potential and is discussed in this Review. Although the field of molecular logic was originally discussed mainly in terms of a technology that might compete with solid-state computers, potential applications have expanded to include clever molecular systems and materials for drug delivery, sensing, probing, encoding, and diagnostics.These upcoming trends, which are herein illustrated by selected examples, deserve general attention.
