Enhanced Two-Photon Absorption with Novel Octupolar Propeller-Shaped Fluorophores Derived from Triphenylamine
摘要:
Novel octupolar fluorophores derived from the symmetrical functionalization of a triphenylamine core with strong acceptor peripheral groups via phenylene-ethynylene linkers have been synthesized and shown to exhibit high fluorescence quantum yields, very large TPA cross-sections in the red-NIR region, and suitable photostability.

Site-specific introduction of deuterium is important in organic and medicinal chemistry. Herein, we present an electrochemical method for the deuterodehalogenation of aryl and heteroaryl benzylic halides, using inexpensive deuteriumoxide as the deuterium source. We also uncover a sequential paired electrolysis regime, which permits switching between net reductive and overall redox-neutral reactions
