In this work, we report on possible isomerization and cyclization pathways in 3-styrylpyridine (3-STPY) and 4-styrylpyridine (4-STPY) isomers.
This review discusses how ultrafast organic photochemical reactions are controlled by conical intersections, highlighting that decay to the ground-state at multiple points of the intersection space results in their multi-mode character.
o-DCSP exhibits AIE, showing no fluorescence in its monomeric form but bright orange emission when aggregated. In contrast, i-DCSP displays consistent blue-white fluorescence in both monomeric and aggregated states.
Phosphorescence in crystalline terephthalic and isophthalic acids is determined by a competition between different radiative and non-radiative mechanisms.
When two photoactive compounds react with each other, the yield and selectivity of the reaction can be manipulated by an appropriate irradiation wavelength.
