Dynamic Covalent Radical Recombination for the Assembly of Tuneable Responsive Porous Organic Cages
Angewandte Chemie International Edition, EarlyView.Dynamic covalent chemistry (DCC) based on reversible radical recombination enables the assembly of responsive, C─C‐linked organic cages. Substituent‐controlled aryldicyanomethyl radicals form discrete, porous architectures with tuneable topology of Tri2 and Tri4 cages, gas selectivity, chromism, and self‐healing behaviour, establishing radical‐based ...

Noncommutative invariants of dihedral groups
International Journal of Algebra and ComputationLet [Formula: see text] and [Formula: see text] be, respectively, the 2-generated free metabelian associative and Lie algebra over the field of complex numbers. In the associative case we find a finite set of generators of the algebra [Formula: see text] of the dihedral group of order [Formula: see text], [Formula: see text]. In the Lie case we find a

On Klein Surfaces and Dihedral Groups.
MATHEMATICA SCANDINAVICA, 1995 We study the following problem. Given an NEC group \(\Gamma\) and the dihedral group \(D_p\), with \(p\) a prime, how many non-conjugate normal subgroups of \(\Gamma\) has \(D_p\) as quotient group? This is equivalent to asking how many non-biconformally equivalent Klein surfaces that are coverings of the orbifold whose fundamental group is \(\Gamma ...

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks
Angewandte Chemie International Edition, EarlyView.A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

The Anatomical Record, EarlyView.Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Bulletin of the Korean Chemical Society, EarlyView.Structure‐oriented design of NHC‐based tetradentate Pt(II) complexes offers narrowband deep‐blue emission for OLEDs. This review highlights how steric shielding and electronic modulation regulate intermolecular interactions, excited‐state dynamics, and device performance, outlining design principles and outlines toward efficient and durable blue ...

Sequencing certain dihedral groups
Discrete Mathematics, 1990 A sequencing of a finite group is an ordering of its elements such that the partial products of its nonempty initial segments exhaust all group elements (without repetition). It is shown that at least three-fourths of the dihedral groups are sequenceable.

Chemistry – A European Journal, EarlyView.Successfully applying self‐assembled monolayers with hole‐selectivity for lead‐free tin perovskite solar cells requires judicious investigation with appropriately powerful characterization methods, in addition to efforts in the development of new materials and processing.

Sodium Tetraazidoaurate(III)—From Na[AuCl4]·2H2O to Na[Au(N3)4] and Beyond One Step at a Time
Chemistry – A European Journal, EarlyView.Novel sodium chlorido‐/azidoaurate(III) dihydrates Na[AuCl4–x(N3)x]·2H2O (x = 0, 1, 2, 3, 4) provide the first example of a complete series of gradual substitution on tetramer complex anions to be described. Controlled dehydration of Na[Au(N3)4]·2H2O leads to Na[Au(N3)4]·H2O and Na[Au(N3)4], the latter being a highly explosive material.

Shunkov Groups with Additional Finiteness Conditions, Containing Dihedral Subgroups
Известия Иркутского государственного университета: Серия "Математика"In this paper, Shunkov groups are studied in the context of the well-known question of B. Amberg and L. S. Kazarin about the structure of groups containing direct products of a finite number of dihedral groups.
