bisimidazole and bisbenzimidazole
donors in combination with Pd(NO3)2 acceptor
via coordination-driven self-assembly. They were characterized by
NMR and mass spectrometry, and the solid-state structures of SP1 and SP3 were confirmed by X-ray diffraction.
Crystal packing revealed the presence of molecular channels with water
molecules in the channels as proton source. All the systems showed
proton conductivity across a wide range of temperature and relative
humidity. Furthermore, the mode of proton conduction in these molecular
spheroids was explored by performing a control experiment using 2,4-dinitrophenol
molecule, which indicates that the proton conductivity in the present
case increases with increasing surface area of these molecular spheroids.
