Substituent Effects on Cyanine Dyes Vary with Position and Chain Length

Advanced 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.

Insights Into Degradation Pathways of Perovskite Thin Films under Outdoor and Indoor Conditions: A Comparative Analysis

Advanced Optical Materials, EarlyView.
This study compares indoor low‐light and outdoor high‐light degradation in perovskite thin films. Under ∼1000 lux [N2], films remain stable; in oxygen, the same low light triggers strain, surface oxidation, and shorter lifetimes. Whereas high light accelerates decomposition to PbI2 and metallic oxides.
