The intramolecular charge transfer (ICT) of 1-aminoanthraquinone (AAQ) in the excited state strongly depends on its solvent properties, and the twisted geometry of its amino group has been recommended for the twisted ICT (TICT) state by recent theore

Abstract The energy flow during natural photosynthesis is controlled by maintaining the spatial arrangement of pigments, employing helices as scaffolds. In this study, we have developed porphyrin-peptoid (pigment-helix) conjugates (PPCs) that can mod

Excited-state proton transfer dynamics of photoacids becomes independent on the solvent basicity when confined in the small reverse micelles. Deprotonation and recombination dynamics of photoacids depend on the micelle size with the water and methano
