Tailoring Exciton Spin Dynamics via Quantum Confinement in CsPbBr3 Nanoplatelets

Abstract Understanding how quantum confinement governs spin-resolved dynamics is essential for the development of perovskite-based spin photonics. Here, we systematically investigate exciton spin relaxation in thickness-tunable CsPbBr3 nanoplatelets via circularly polarized trans...

Hydroxyl-directed differentiation of photocyclization pathways in triphenylamine monitored by transient absorption spectroscopy

Photoinduced [6π]-electrocyclization of triphenylamine provides an efficient route to the construction of carbazole frameworks. In this work, 4-(diphenylamino)phenol (TPA-OH) was selected as a model compound to examine how hydroxyl substitution breaks the symmetry of triphenylami...
