Exploring the Impact of Topological Variations on the Stability of the Ground Singlet and Lowest‐Lying Triplet States of Catacondensed Hexabenzenoids

European Journal of Organic Chemistry, Accepted Article.
Polycyclic aromatic hydrocarbons (PAH) like tetracenes, pentacenes, hexacenes, and some higher acenes play a central role in organic electronics due to their unique electronic properties. The impact of topological variations on the relative stability of PAH isomers in different electronic states is poorly understood, with limited insights into how Clar

Market Consistent Valuation for Bitcoin Options With Long Memory in Conditional Volatility and Conditional Non‐Normality

Journal of Futures Markets, EarlyView.
ABSTRACT This paper investigates the economic consequences for Bitcoin options' prices of a long memory in conditional volatility and conditional non‐normality of Bitcoin returns. The arbitrage‐free prices of Bitcoin options are determined by market consistent valuation and the conditional Esscher transform. Monte Carlo estimates for option prices from

Collective nature of phonon energies beyond harmonic oscillators

Computational Materials Today
Phonon quasi-particles have been monumental in microscopically understanding thermodynamics and transport properties in condensed matter for decades. Phonons have one-to-one correspondence with harmonic eigenstates and their energies are often described ...

Intramolecular Phenyl Transfer from Boron to Lithium, Sodium, and Copper: Defining the Limits of Transmetalation

Helvetica Chimica Acta, EarlyView.
Abstract Transmetalation is a key elementary step in organometallic chemistry, for which reason there is a keen interest in better understanding the factors governing this reaction. We have previously reported the unusual transfer of a phenyl anion from boron to lithium in the gas‐phase dissociation of [LiBr(tBu)(Ph)Bpin]− (Chem. Eur. J.
