Acid/Base‐Responsive Circularly Polarized Luminescence Emitters with Configurationally Stable Nitrogen Stereogenic Centers

open access: yesAdvanced Materials, EarlyView.
Circularly Polarized Luminescence (CPL) emitters based on Tröger's base analogues bearing two peripheral fluorophores (anthracene, pyrene or 9,9‐dimethylfluorene) are prepared following a straightforward and versatile synthetic approach from common precursors.

A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

open access: yesAdvanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.

Mechanochromic, Low‐Cost, and Structurally Colored Displays Using Biodegradable Hydroxypropyl Cellulose

open access: yesAdvanced Materials, EarlyView.
Mechanochromic hydroxypropyl cellulose (HPC) integrated with microfluidic devices creates scalable, eco‐friendly reflective color displays. We demonstrate mechanochromic displays with 500 µm pixel size and 5Hz switching rates with room for optimisation. The proposed mechanochromic HPC displays are an initial step toward more environmentally responsible

Halide Perovskite Photocatalysts for Clean Fuel Production and Organic Synthesis: Opportunities and Challenges

open access: yesAdvanced Materials, EarlyView.
This review provides the state‐of‐the‐art overview of halide perovskite‐based photocatalysts for hydrogen production from water and halogen acid solutions, CO2 reduction into value‐added chemicals, and organic chemical transformations. Different types of halide perovskite photocatalysts and their relative efficiencies for hydrogen generation and CO2 ...
