Abstract:
An FTIR study reveals the complex zwitterion (R2C−–Py+–H) in a polymeric chain of poly(4-vinylpyridine), which results from self-protonation of the latter in a pyridine solution. Presumably this complex ion, together with the observed strongly hydrogen-bonded network, is responsible for the formation of a gel with unique tunable emission properties.
