BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA
Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.

A simple formula for calculating resonance energy of benzenoid hydrocarbons
Macedonian Journal of Chemistry and Chemical Engineering, 2006 The topological resonance energy (TRE) of a catacondensed benzenoid hydrocarbon with h six-membered rings and K Kekulé structures can be calculated by the (approximate) formula TRE = Ah + B + CK e–Dh, where A = 0.136, B = –0.223, C = 0.281, and D = 0.454.

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

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.We disclose a novel boron macrocycle derived from the sustainable furan building block. The boraporphyrinoid exhibits a global antiaromatic ring current and dynamic conformational flexibility. Twofold reduction induces a switch to strong global aromaticity, accompanied by stiffening of the porphyrinoid backbone.

COMPUTING THE ANTI-KEKULÉ NUMBER OF CERTAIN NANOTUBES AND NANOCONES
Studia Universitatis Babes-Bolyai Chemia, 2015 Let G(V,E) be a connected graph. A set M subset of E is called a matching if no two edges in M have a common end-vertex. A matching M in G is perfect if every vertex of G is incident with an edge in M.

Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods
Chemistry – A European Journal, EarlyView.We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Synthesis and Thermolysis of Ylidyl‐Substituted Stannylenes
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The synthesis of an amino(ylidyl)stannylene is reported. The title compound was characterized via X‐ray diffraction and features a Sn2C2 heterocycle. Thermal treatment of the stannylene leads to the elimination of the amine. The products of the thermolysis are discussed.
