T‐Shaped 8‐Aryl(ethynyl)‐Substituted Psoralens With Tunable Charge‐Transfer Absorption

European Journal of Organic Chemistry, EarlyView.
Starting from 8‐methoxypsoralen, new 8‐arylated and 8‐alkynylated psoralen derivatives are accessible by cross‐coupling. These T‐shaped π‐expanded chromophores are luminescent and photophysics reveal a highly polar excited state with tunable charge‐transfer character.

Invariant Photoinduced Energy‐Transfer Followed by Electron‐Transfer Events in Boron Dipyrromethene Derivatives Covalently Anchored to MoS2 and WS2

Small, EarlyView.
In this work, we study the electronic interactions of MoS2 and WS2 covalently interfaced with boron dipyrromethene derivatives across different regions of the light spectrum. Under light irradiation, energy and electron transfer processes are observed, revealing environment‐invariant modifications of the BODIPY core induced by different functional ...
