Site-selective methylene C-H oxidation of an alkyl diamine enabled by supramolecular recognition using a bioinspired manganese catalyst.
Vicens A, Vicens L, Olivo G, Lanzalunga O, Di Stefano S, Costas M. Vicens A, et al. Faraday Discuss. 2023 Aug 11;244(0):51-61. doi: 10.1039/d2fd00177b. Faraday Discuss. 2023. PMID: 37185809
This recognition has been used to pursue site-selective oxidation of a methylenic site, using hydrogen peroxide as oxidant in the presence of carboxylic acids as co-ligands. Excellent site-selectivity towards the central methylenic sites (C6 and C7) is observed, ove …

How the Length of Through-Space Conjugation Influences the Clusteroluminescence of Oligo(Phenylene Methylene)s.
Wang L, Xiong Z, Zhi Sun J, Huang F, Zhang H, Zhong Tang B. Wang L, et al. Angew Chem Int Ed Engl. 2024 Feb 19;63(8):e202318245. doi: 10.1002/anie.202318245. Epub 2024 Jan 16. Angew Chem Int Ed Engl. 2024. PMID: 38165147
Here, we unveil a non-linear relationship between TSC length and emission characteristics in non-conjugated systems, in contrast to the reported proportional correlation in TBC systems. More specifically, oligo(phenylene methylene)s (OPM[4]-OPM[7]) exhibit stronger TSC and …
