TADF‐Emitting Dendrimers for Scalable Bar‐Coating Fabrication of Light‐Emitting Electrochemical Cells

open access: yesAdvanced Materials Technologies, EarlyView.
TADF‐emitting dendrimers promise to enable scalable solution‐based fabrication of efficient electroluminescent devices by the virtue of an attractive set of properties. Here, we report on how light‐emitting electrochemical cells, comprising the TADF‐dendrimer tBuCz2m2pTRZ, can be fabricated by scalable bar‐coating under ambient air and deliver uniform ...

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

Substituent Effects on Cyanine Dyes Vary with Position and Chain Length

open access: yesAdvanced Optical Materials, EarlyView.
In cyanines, substituent effects vary as a function of substituent position and cyanine length. Electron‐donating‐ and ‐withdrawing groups at meso‐ and α‐positions of 4n+1/4n−1 long cyanines (n = 1, 2, 3…) cause opposing, hypsochromic and bathochromic shifts of the 1st UV–vis absorption bands.
