Crystal-like periodic mesoporous organosilica bearing pyridine units within the framework

Periodic mesoporous organosilica with densely packed pyridine units within the framework and crystal-like molecular-scale periodicity was synthesized. The framework pyridines were chemically active and fully accessible for protonation and Cu2+

Efficient thermal conversion of poly(pyridinediylbutadiynylene)s to nitrogen-containing microporous carbon

Poly(pyridinediylbutadiynylene)s, a conjugated polymer alternatively consisted of the pyridine and butadiyne units, were synthesized by oxidative polycondensation of diethynylpyridine with the Hay catalyst. They converted to microporous carbons in high yi

Orbital interactions in ethynylpyridines

He I and He II photoelectron spectra of several isomeric ethynyl- and diethynylpyridines have been measured. The spectra were analyzed with the aid of empirical arguments: relative band intensities and comparison with spectra of related compounds (ethynyl
