Matrix-free phosphorescent carbon nanodot inks enable scalable, invisible printing with ultrahigh resolution and high fidelity, highlighting their potential for large-scale information storage and time-delayed display applications.

A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent label remains covalently bonded to its target molecule and does not fall apart even under demanding conditions inside living cells. This allows scientists to track labeled molecules over long periods with high reliability – an advantage for research in biology, chemistry, and medicine. The study was published in Angewandte Chemie International Edition.

The German Research Foundation (DFG) is funding the transregional Collaborative Research Centre (CRC/TRR) 211 ‘Strong-Interaction Matter under Extreme Conditions’ for another 3.5 years. The DFG announced the decision today (21 November 2025). The consortium of the universities of Bielefeld, Darmstadt, and Frankfurt am Main will receive around 10 million euros from January 2026 for the third funding phase.

Professor Tonggang Jiu's team at Shandong University achieved a significant improvement in the efficiency and stability of perovskite solar cells by regulating the NiO_x/perovskite interface chemistry by introducing a novel self-assembling molecule, (4-(2,7-dibromo-9,9-dimethylacridin-10(9H)-yl)butylphosphonic acid (2Br-4PADMAc), into the NiO_x/perovskite interface. This effectively suppressed Ni^>3+ generation and interfacial redox reactions, optimized energy level matching, and promoted high-quality film crystallization. Compared to the traditional molecule 2PACz, 2Br-4PADMAc exhibits stronger interfacial anchoring and a larger molecular dipole moment, which can improve hole transport efficiency and reduce PbI₂ accumulation. The inverse perovskite solar cell modified with this molecule achieved a photoelectric conversion efficiency of 25.28% and excellent stability. This research provides a new strategy for optimizing the efficiency and stability of NiO_x-based perovskite solar cells through interfacial molecule design. The article was published as an open access research article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.
