One Step

We present a one-step Sonogashira dispersion polymerization generating monodisperse conjugated polymer particles with acetylene units on their surface. These moieties can be bio-functionalized using copper-free thiol-yne click chemistry providing fluorescent probes for cell labelling and imaging.

Electrochemical Synthesis Of Ammonia

3D-graphene provide abundant space for N2, and the carbon–sulfur bonds provides a continuous supply of electrons for N2 reduction. A remarkably large NH3 yield of 38.81 μgNH3 mgcat−1 h−1 and FE of 7.72% for N2 reduction was obtained.

Defect-rich fluorographene behaves as a metal-free catalyst for the artificial conversion of N2 to NH3 at ambient conditions. In 0.1 M Na2SO4, it achieves a faradaic efficiency (FE) of 4.2% with an NH3 formation rate (RNH3) of 9.3 μg h−1 mgcat.−1 at −0.7 V vs. RHE, with strong long-term electrochemical durability.
