X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

open access: yesAdvanced 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 ...

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...
