Summary
Intelligent chemical systems need precise energy control. Diverse chemical fuels precisely control system lifetimes by varying energy dissipation rates, enabling temporal regulation of functions like signal generation and self-assembly.
Area of Science:
- Chemical Systems Engineering
- Supramolecular Chemistry
- Biocatalysis
Background:
- Adaptive chemical systems require continuous energy for sustained function.
- Precise control over energy dissipation is crucial for managing the lifetime of transient functions.
- Enzyme-catalyzed energy dissipation offers a pathway to control system dynamics.
Purpose of the Study:
- To investigate the use of structurally diverse chemical fuels for controlling the lifetime of dissipative systems.
- To demonstrate temporal control over transient signal generation and self-assembled aggregate formation.
- To establish a link between fuel structure, enzyme-mediated dissipation rate, and system lifetime.
Main Methods:
- Utilized structurally diverse chemical fuels as energy sources.
- Employed an enzyme to catalyze the rate-dependent dissipation of fuel energy.
- Investigated two systems: transient signal generation and transient self-assembly of aggregates.
- Analyzed the dependence of system lifetime on fuel structure and concentration.
Main Results:
- Demonstrated that different chemical fuels can precisely control system lifetimes.
- Achieved temporal control over signal generation spanning two orders of magnitude.
- Showed that fuel structure dictates energy dissipation rate via enzymatic action.
- Established that controlled lifetimes of self-assembled aggregates are crucial, independent of fuel concentration.
Conclusions:
- Chemical fuels offer a versatile tool for precise temporal control in dissipative chemical systems.
- Enzyme-catalyzed energy dissipation provides a mechanism to tune system lifetimes based on fuel properties.
- This methodology enables the design of adaptive chemical systems with predictable functional durations.

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Free-energy diagrams, or reaction coordinate diagrams, are graphs showing the energy changes that occur during a chemical reaction. The reaction coordinate represented on the horizontal axis shows how far the reaction has progressed structurally. Positions along the x-axis close to the reactants have structures resembling the reactants, while positions close to the products resemble the products. Peaks on the energy diagram represent stable structures with measurable lifetimes, while...

3.1K
Electrocyclic reactions are reversible reactions. They involve an intramolecular cyclization or ring-opening of a conjugated polyene. Shown below are two examples of electrocyclic reactions. In the first reaction, the formation of the cyclic product is favored. In contrast, in the second reaction, ring-opening is favored due to the high ring strain associated with cyclobutene formation.

The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified...

4.3K
The addition of a hydrogen halide to 1,3-butadiene gives a mixture of 1,2- and 1,4-adducts. Since more substituted alkenes are more stable, the 1,4-adduct is expected to be the major product. However, the product distribution is strongly influenced by temperature; low temperature favors the 1,2-adduct, whereas the 1,4-adduct is predominant at high temperature.

01:26Photochemical Electrocyclic Reactions: Stereochemistry
2.3K
The absorption of UV–visible light by conjugated systems causes the promotion of an electron from the ground state to the excited state. Consequently, photochemical electrocyclic reactions proceed via the excited-state HOMO rather than the ground-state HOMO. Since the ground- and excited-state HOMOs have different symmetries, the stereochemical outcome of electrocyclic reactions depends on the mode of activation; i.e., thermal or photochemical.
