Advanced Functional Materials, EarlyView.Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...
