Poly(5-ethylidene-2-norbornene) (PENB) was synthesized via a vinylic pathway using a cationic palladium-based catalyst, displaying high activity up to 1.06×10^6 g-PENB/mol Pd. The effects of the monomer to catalyst ratio, temperature, reaction time, and concentration on the polymerization were investigated systematically. The control tests and spectroscopic analyses of the PENB indicate that 5-ethylidene-2-norbornene is polymerized via an addition polymerization using endocyclic double bonds. The post-modification was also performed using a free radical graft polymerization. The resulting PENB copolymers were characterized by IR, ^1H NMR, and GPC analyses.
The Soft Material Obtained from an Europium (III)-Containing Ionic Liquid
Shao, Huifang,Wang, Yige,Li, Dan Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.3
The addition of organic ligand (${\beta}$-diketone or heterocyclic compound) to the europium (III)-containing ionic liquid resulted in bright luminescent soft materials with the molar ratio of europium/ionic liquid (IL)/ligand being 1:3:1 that exhibit bright red light under UV lamp. The luminescent properties such as emission features and lifetime of $^5D_0$ $Eu^{3+}$ excited level are dependent on the organic ligands. The materials were characterized by FT-IR and luminescence spectroscopy. The data shows that at least parts of the ILs (carboxylic acid) are replaced with ${\beta}$-diketone ligand rather than the formation of europium complex with the molar ratio of $Eu^{3+}$:IL: ligand being 1:3:1, while no ILs could be replaced by the heterocyclic ligand such as Bpy and Phen.

The addition of organic ligand (β-diketone or heterocyclic compound) to the europium (III)-containing ionic liquid resulted in bright luminescent soft materials with the molar ratio of europium/ionic liquid (IL)/ligand being 1:3:1 that exhibit bright red light under UV lamp. The luminescent properties such as emission features and lifetime of ^(5)D_0 Eu^(3+) excited level are dependent on the organic ligands. The materials were characterized by FT-IR and luminescence spectroscopy. The data shows that at least parts of the ILs (carboxylic acid) are replaced with β-diketone ligand rather than the formation of europium complex with the molar ratio of Eu^(3+):IL: ligand being 1:3:1, while no ILs could be replaced by the heterocyclic ligand such as Bpy and Phen.

<P><B>Summary</B></P> <P>We conducted the largest investigation of predisposition variants in cancer to date, discovering 853 pathogenic or likely pathogenic variants in 8% of 10,389 cases from 33 cancer types. Twenty-one genes showed single or cross-cancer associations, including novel associations of <I>SDHA</I> in melanoma and <I>PALB2</I> in stomach adenocarcinoma. The 659 predisposition variants and 18 additional large deletions in tumor suppressors, including <I>ATM</I>, <I>BRCA1</I>, and <I>NF1</I>, showed low gene expression and frequent (43%) loss of heterozygosity or biallelic two-hit events. We also discovered 33 such variants in oncogenes, including missenses in <I>MET</I>, <I>RET</I>, and <I>PTPN11</I> associated with high gene expression. We nominated 47 additional predisposition variants from prioritized VUSs supported by multiple evidences involving case-control frequency, loss of heterozygosity, expression effect, and co-localization with mutations and modified residues. Our integrative approach links rare predisposition variants to functional consequences, informing future guidelines of variant classification and germline genetic testing in cancer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> 871 predisposition variants/CNVs discovered in 8% of 10,389 cases of 33 cancers </LI> <LI> Pan-cancer approach identified shared variants and genes across cancers </LI> <LI> 33 variants affecting activating domains of oncogenes showed high expression </LI> <LI> 47 VUSs prioritized using cancer enrichment, LOH, expression and other evidence </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>
