Exploring the Helical Structure of Ethylene Oxides: Beyond Steric and Related Effects

ChemPhysChem, EarlyView.
A helical structure in ethylene oxides begins to emerge early as the chain length increases in solution. This formation is facilitated by the attenuation of dipolar repulsion and stabilization of dipoles. However, it is primarily driven by hyperconjugative interactions, which often underpin gauche effects and dominate over Lewis‐type interactions ...

Donor–Acceptor Interactions of C60F18 with Polycyclic Aromatic Hydrocarbons: Size Effects in Bulk Crystallization and Surface Constraints

ChemPlusChem, EarlyView.
Donor–acceptor (D/A) interactions between spheroidal C60F18 and three planar polycyclic aromatic hydrocarbons (PAHs)—coronene (CORO), perylene , and pyrene—show a strong dependence on PAH size. X‐Ray diffraction reveals increasing layered stacking (either D/A/D/A or D/A/A/D/A/A).

Enhancing Near‐Infrared Two‐Photon Absorption of Aza‐Boron‐Dipyrromethene Compounds Through Intramolecular Charge Transfer Via Electron Donating Substitution

ChemPlusChem, EarlyView.
Aza‐BODIPY compounds is designed with 4‐methoxyphenyl, 2,4‐dimethoxyphenyl, and 4‐N,N‐diphenylaminophenyl groups at the 1 and 7 positions. The effects of substituents and solvent polarity (tetrahydrofuran and chloroform) on the linear absorption, fluorescence behaviors as well as nonlinear absorption properties are investigated.

Symmetric Bis‐Kryptopyrrol‐2‐Yl Squaraine as a Viscosity Probe and Dual‐State Emitter

ChemPhotoChem, EarlyView.
Previously unknown capabilities of one of the original squaraine dyes as a viscosity probe and dual‐state emitter are revealed, with aggregated forms of the dye being responsible for the near‐IR emission in the solid state. Easily accessible small organic fluorophores with multiplexing capabilities are of interest for a variety of fields.
