Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging
Advanced Optical Materials, EarlyView.By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

High Contrast and High Efficiency Optical Weighting for Integrated Photonic Computing
Advanced Optical Materials, EarlyView.Herein, a combined pulse optical weighting scheme is proposed for photonic synapses. Employing a 4 μm$\umu{\rm m}$ long non‐volatile phase‐change material covered on a straight waveguide, a transmission contrast of 31.2 dB is achieved. By exploiting the non‐Arrhenius behavior of the material, the crystallization energy is reduced to 107 pJ, with ...

Advanced Optical Materials, EarlyView.This work presents the development of efficient blue thermally activated delayed fluorescent (TADF) materials that perform well without doping, enabling simplified, matrix‐free hyperfluorescence (MFHF) OLEDs. When combined with encapsulated narrow‐band emitters, the TADF materials serve as effective hosts resulting in pure blue, ultranarrow emission ...

Bubble Printing of Anisotropic Clay Nanotubes
Advanced Optical Materials, EarlyView.Bubble printing patterns of lyotropic liquid crystal nanotubes form toroidal or linear patterns depending on laser movement and colloidal stability. Long nanotubes create radial filament bundles, while poor electrostatic repulsion hinders deposition.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies
Advanced Optical Materials, EarlyView.A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.
