Monochlorination led to slightly blue-shifted absorption, deepened EHOMO, weakened aggregation and markedly increased natural dipole moment, contributing to an 22.65% increased PCE up to 9.53%.
Identification of chlorinated products from tyrosine and tyrosyl dipeptides was explored using the DFT method.
Visible light-promoted C(sp3)–H bond chlorination with MgCl2 as a chlorine source in AcOH/CH3CN in the presence of FeCl3 is reported.
A general palladium-catalysed selective C–H halogenation reaction is reported, which was successfully achieved for a large variety of functionalized aromatic rings incorporating diverse N-directing groups.
A new mode of N-heterocyclic carbene (NHC) organocatalysis was discovered, in which the normally inert chlorinated solvents were activated by carbene to realize the chlorination of hexa-dehydro-Diels-Alder derived benzynes.
