High‐Gain PMMA‐Modified Graphene Photodetectors for Dual‐Wavelength Secure Communication Utilizing Distinct Temporal Photoresponses

open access: yesAdvanced Science, EarlyView.
The bipolar photoresponses with temporally distinguishable characteristics in a PMMA‐modified graphene photodetector are successfully achieved. Through systematic harnessing of these wavelength‐dependent temporal dynamics as encrypted and key signals, an effective encryption system for optical communication systems is developed.

Respiration Drives Dynamic Metal–Organic Framework for Smart Photoresponse to Volatile Toxic Vapors and Their Photodynamic Sterilization

open access: yesAdvanced Science, EarlyView.
The flexible AIEgen (H4TPPE) with obvious molecular rotor structure is used as a linker to connect with the octahedral Zr6O4(OH)8(H2O)4 cluster‐based SBU to obtain the first smart luminescent MOF (Zr‐TPE‐MOF) with dynamic respiration driven by toxic vapors.

Simultaneous Multi‐Resonant Thermally Activated Delayed Fluorescence and Room Temperature Phosphorescence from Biluminescent Nitrogen‐Containing Indolocarbazoles

open access: yesAdvanced Science, EarlyView.
An extremely rare type of organic biluminescent emission is reported that consists of delayed emission resulting from both the fluorescence (multi‐resonance thermally activated delayed fluorescence) and phosphorescence spectra at room temperature, and the lifetimes of the two processes exhibit opposing dependence with temperature.

In Situ Construction of Multi‐Functional Polymer Network Toward Durable Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Acrylamide monomers were introduced into the perovskite precursor solution to 3D polymer networks at grain boundaries for stabilizing grain boundaries. By constructing weak chemical bond interactions with perovskite films, the polymer networks effectively reduce defect density and simultaneously suppress the degradation of perovskites.

Sustainable Development of High‐performance Poly(ester‐imine) Biobased Thermosets

open access: yesAdvanced Science, EarlyView.
Schiff‐based epoxy monomers derived from renewable natural resources are used to design robust structures by cross–linking with bio‐anhydrides. The resulting eco‐friendly, high‐performance thermosets feature two cleavable bonds, offering versatility for various applications.
