Reviews in Angewandte Chemie, written by leading experts, summarize the important results of recent research on topical subjects in all branches of chemistry, point to unresolved problems, and discuss possible developments. Although review articles are generally written upon invitation of the editor, unsolicited manuscripts are also welcome provided they are in keeping with the character of the journal.

Two dimensions provide more insight than one: Coherent electronic multidimensional spectroscopy in different variations allows the separation of photochemical reaction channels. This is demonstrated exemplarily for a molecular switch capable of light-induced ring-opening and ring-closure reactions, cis—trans isomerization, vibrational wave-packet dynamics, radical cation formation, and population relaxation.
From Ultrafast Structure Determination to Steering Reactions: Mixed IR/Non-IR Multidimensional Vibrational Spectroscopy

Finger on the pulse: Combining IR with non-IR pulses in multidimensional vibrational spectroscopy creates techniques with possibilities far beyond those of IR experiments alone. These include powerful tools for studying photochemistry, dynamics at surfaces and interfaces, as well as non-equilibrium structural dynamics. This Review discusses important differences between useful pulse sequences and gives examples of their application.

Rule of three: Natural nucleic acids and the genetic information they encode are limited by the use of only four nucleotides that form two base pairs, (d)G-(d)C and d(A)-dT/U. In the past decade, three classes of unnatural base pairs have been developed to a high level of proof-of-concept. This Review summarizes their development and the potentially revolutionary applications that they are now enabling.

DNA gates: Stimuli-responsive DNA-functionalized nano- and microcontainers composed of mesoporous SiO2 nanoparticles, microcapsules, or micelles/vesicles act as drug carriers for targeted controlled release. Different stimuli such as chemical, photonic, thermal, and biocatalytic triggers are used to release the loaded drugs.

Center of attraction: Dispersion attraction makes all the difference in the stability of molecular structures, reactivity, and the design of catalysts. Although small for one pair of interactions, dispersion grows rapidly as the molecular size increases.

Covalent modification of graphene on substrates allows fine control of its chemical structure and opening of the bandgap for electronic applications. The graphene type and morphology, the nature of the substrate, and mechanical forces are key factors affecting reactivity. Analysis of these parameters and comparison of the different functionalization routes is essential to make an informed choice when working with functionalized graphene on a support.

Ill-gotten gains: Volatolomes enable identification of the collection of volatile organic compounds in a biological cell, tissue, or organism, that are the by-/end products of cellular processes in the living organism. The new analytical approach of volatolomics allows the large-scale scientific study of chemical processes involving volatile organic compounds.

There’s always the sun: Graphene-based photocatalysts for solar-fuel production are of significant interest in solving the global energy problem. The recent advances in the fabrication and application of graphene-based photocatalysts, including photocatalytic reduction of CO2 to hydrocarbon fuels and photocatalytic splitting of water to H2 are explored.
