Herein we develop a new pillar[5]arene-mediated supramolecular polymerization strategy to control the assembly of dyes 4,7-di-2-thienyl-2,1,3-benzothiadiazole and 4,7-di-2-thienyl-2,1,3-benzoselenadiazole in solid state. The resulting polymeric structures drive dye aggregates state from parallel alignments highly ordered "head-to-tail" structures, which effectively suppresses excimer formation thus aggregation-caused quenching effects enhances solid-state emission efficiency by almost 1...
A critical fundamental question regarding how the energetics governs hole transfer (HT) rate, efficiency, and device performance in nonfullerene acceptor (NFA) organic solar cells (OSCs) remains unclear.

Absolute pKas of selected salts with different counter-anions were measured high precision in four aprotic ionic liquids (AILs), which enables a detailed examination solvation effect ILs on salts. Interestingly, the ylide precursor salts, protic amine, and phenol this study, though differing dramatically size electron dispersion, found to have no respective substrates. This indicates that species generated upon acidic dissociation weakly polar AILs low dielectric constant (ε: 10-15) are not...

Nonadiabatic molecular dynamics (NAMD) simulations are crucial for revealing the underlying mechanisms of photochemical and photophysical processes. Typical NAMD simulation software packages rely on on-the-fly ab initio electronic structure nonadiabatic coupling calculations, thus become challenging when dealing with large complex systems. We here introduce a new Simulation Package non-Adiabatic Dynamics in Extended systems (SPADE), which is designed to address limitations traditional...
Trajectory surface hopping combined with ab initio electronic structure calculations is a popular and powerful approach for on-the-fly nonadiabatic dynamics simulations. For large systems, however, this remains significant challenge because of the unaffordable computational cost large-scale calculations.
