Investigating the Effects of Donors and Alkyne Spacer on the Properties of Donor-Acceptor-Donor Xanthene-Based Dyes

Molecules, 2023
NIR dyes have become popular for many applications, including biosensing and imaging. For this reason, the molecular switch mechanism of the xanthene dyes makes them useful for in vivo detection and imaging of bioanalytes.

Mimikry eines Lichtsammelkomplexes zur Beschleunigung der Photooxidation in asymmetrischen Lipidmembran‐Nanoreaktoren

Angewandte Chemie, EarlyView.
Biomimetische Liposomen‐Nanoreaktoren, die natürliche Lichtsammelkomplexe nachahmen, ermöglichen eine effiziente Photooxidation von NADH. Membrangebundenes Fluorescein überträgt Energie über FRET an membrangebundenes Eosin Y und oxidiert so NADH.

Extended Fused Carbazole‐BODIPY, High Brightness NIR Organic Dyes

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Highly fused boron‐dipyrromethene (BODIPY) with a strong donor group has been synthesized, and their photophysical behaviors fully characterized. They exhibit outstanding brightness for fluorophores emitting in the NIR region. Water‐soluble nanoparticles filled with one of these dyes demonstrate high efficiency as the NIR II visualization agent ...

Wash‐Free Multi‐Target Super‐Resolution Microscopy With Photocaged DNA Labels

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Photocaged DNA labels enable wash‐free multi‐target super‐resolution microscopy. A single type of DNA–fluorophore imager strand hybridizes to two orthogonal light‐responsive docking strands, whose hybridization state can be modulated with light from “ON” to “OFF” and vice versa.

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

FlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...
