Theoretical Analysis of the Influence of Chelate-Ring Size and Vicinal Effects on Electronic Circular Dichroism Spectra of Cobalt(III) EDDA-Type Complexes

Benchmarking computational methods and influence of guest conformation on chirogenesis in zinc porphyrin complexes

Different computational methods and influence of the guest conformation and solvent effect to analyze chirogenesis in zinc porphyrins by several chiral compounds have been investigated.

Theoretical study on the photophysical properties of boron-fused double helicenes

Seven boron-fused double helicenes containing different electron-donors or acceptors and their combinations were investigated to shed light on the effective way to enhance the second-order NLO response.

Understanding the photophysical properties of chiral dinuclear Re(i) complexes and the role of Re(i) in their complexes

We have investigated the electronic structure, UV-Vis/CD spectra and the second-order NLO properties of chiral dinuclear Re(i) complexes and elucidated structure–property relationships with the aid of DFT calculations.

Electronic circular dichroism of chiral alkenes: B3LYP and CAM-B3LYP calculations

Time-dependent density functional theory (TDDFT) calculations of electronic circular dichroism (ECD) are widely used to determine absolute configurations (ACs) of chiral molecules. Two very popular DFT exchange-correlation functionals, one hybrid (B3LYP) and one long-range corrected (CAM-B3LYP), along with a hierarchical sequence of basis sets were investigated, and the ECD spectra predicted for eight alkenes and compared to gas-phase experimental spectra. Little variation in predicted ECD spectra was found with the basis set size enlargement, but the sensitivity to the functional is greater. Good agreement was obtained only with the CAM-B3LYP functional, leading to the conclusion that TDDFT calculations of ECD spectra can routinely provide reliable ACs if and only if an appropriate functional is used. For camphene, twistene, syn-(E)-bisfenchylidene, and phyllocladene, solvent effects were estimated.
