Structure‐Tuned Lead Halide Perovskite Nanocrystals
Yasser Hassan,Yasser Hassan,Yin Song,Ryan D. Pensack,Ahmed I. Abdelrahman,Yoichi Kobayashi,Mitchell A. Winnik,Gregory D. Scholes,Gregory D. Scholes +8 more
TL;DR: Colloidally stable suspensions of lead halide perovskite nanocrystals are prepared from high-quality lead Halide nanocrystal seeds that are well suited for investigations of the intrinsic photophysics and spectroscopy of organic-inorganic metal halideperovskites.

Plasmonic p-n Junction for Infrared Light to Chemical Energy Conversion.
Zichao Lian,Masanori Sakamoto,Junie Jhon M. Vequizo,C. S. Kumara Ranasinghe,Akira Yamakata,Takuro Nagai,Koji Kimoto,Yoichi Kobayashi,Naoto Tamai,Toshiharu Teranishi +9 more
TL;DR: Spectroscopic results revealed that plasmon-induced hot-electron injection at p-n heterojunctions realizes exceptionally long-lived charge separation (>273 μs), which results in efficient IR light to hydrogen conversion, paving the way for the exploration of undeveloped low-energy light for solar fuel generation.

A Simple and Versatile Strategy for Rapid Color Fading and Intense Coloration of Photochromic Naphthopyran Families.
TL;DR: A new simple and versatile strategy to substantially reduce the amount of the undesirable long-lived colored transoid-trans form by introducing an alkoxy group at the 1-position of azino-fused chromenes, i.e., 8H-pyranoquinazolines is found.

Fast Negative Photochromism of 1,1'-Binaphthyl-Bridged Phenoxyl-Imidazolyl Radical Complex.
TL;DR: A negative photochromic 1,1'-binaphthyl-bridged phenoxyl-imidazolyl radical complex (BN-PIC) which enables fast photoswitching by visible light and is expected to have an impact in the fields of photoresponsive materials of solid states and molecular aggregates.
