Comparative Study on Autoignition Characteristics of Methylcyclohexane and Cyclohexane

, 2015
Ignition delay times were measured behind reflected shock waves for cyclohexane and methylcyclohexane at pressures of 1.1, 5.0, and 16.0 atm, temperatures from 1075 to 1750 K, and equivalence ratios of 0.5, 1.0, and 2.0.

Conformational Landscapes in the Ground and Excited States Dictate Circularly Polarized Excimer Emission: A Thermodynamic–Kinetic Interplay in Carbazole Dimer Systems

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
Covalently linked carbazole dimers exhibit intense excimer‐based circularly polarized luminescence (CPL). A simple propylene‐tethered dimer achieves glum ≈ 0.01 in the violet region—among the highest for small organic emitters without heavy atoms. Conformational mapping reveals CPL is governed by thermodynamic/kinetic control of emissive conformers ...

Ambident Reactivity in the Phenyl + NO Radical Recombination

Chemistry – A European Journal, EarlyView.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.

Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles

Chemistry – A European Journal, EarlyView.
A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.

Lactones with Methylcyclohexane Systems Obtained by Chemical and Microbiological Methods and Their Antimicrobial Activity

Molecules, 2015
Eight new lactones (δ-chloro-, δ-bromo- and δ-iodo-γ-lactones), each with a methylcyclohexane ring, were obtained by chemical means from (4-methylcyclohex-2-en-1-yl) acetic acid or (6-methylcyclohex-2-en-1-yl) acetic acid.

Synthesis and Properties of Cross‐Shaped Donor–Acceptor Dyes: Tunable Emission From Visible to Near‐Infrared in Solution and Solid‐State

European Journal of Organic Chemistry, EarlyView.
A comprehensive investigation (synthesis, electrochemistry, photophysics, and theory) of seven new cross‐shaped dyes based on N,N,N’,N’‐tetraphenyl‐1,4‐phenylenediamine cores substituted with different electron‐withdrawing groups, reveals tunable emission properties spanning the visible to near‐infrared range, both in solution and in the solid state ...
