摘要

Abstract:" C cross-polarization/magic-angle spinning (CP-MAS) NMR experiments at 50.36 MHz reveal that the solid-state reaction of the crystalline polymer poly (N-dicarbazolyl-2, 4- hexadiyne)(poly-DCH) with liquid bromine results in the formation of covalent C-Br bonds in the polymer. The presence of bromine in these compounds results in loss of the signals arising from those carbon atoms directly bonded to or adjacent to bromine due to ...
