The present invention relates to certain dithiocarbamate compounds of formula (I) comprising a nitrogen containing heterocyclic ring, and exhibiting strong absorption in the visible range of the light spectrum. The compounds of the invention are useful as photoinitiators, in particular in polymerization reactions.
The RAFT agents RAFT‐1 and RAFT‐2 were used for RAFTpolymerization to synthesize well‐defined bimodalmolecular‐weight‐distribution (MWD) polymers. The system showed excellent controllability and “living” characteristics toward both the higher‐ and lower‐molecular‐weight fractions. It is important that bimodal higher‐molecular‐weight (HMW) polymers and block copolymers with both well‐controlled molecular

A group of atomicallyprecise Cu8 cluster isomers with two core structures (cube- and ditetrahedron-shaped) were investigated for highly active and selective CO2 reduction. A difference in catalytic performance was attributed to variable metal core arrangements hidden in Cu8 nanoclusters. The ditetrahedron-shaped cluster exhibits a high Faradaic efficiency for formic acid generation (FEHCOOH) almost
研究了一组具有两个核心结构(立方体形和双四面体形)的原子级精确的 Cu 8簇异构体,用于高活性和选择性的 CO 2还原。催化性能的差异归因于隐藏在 Cu 8纳米团簇中的可变金属核排列。双四面体形簇的甲酸生成 (FE HCOOH ) 的法拉第效率高,几乎是立方体形簇的两倍。
