The synthesis and structural variations in solid‐state emission of zwitterionic imidazolium pyridinolates are described. N‐Alkylimidazolium 2‐pyridin‐3‐olate 1 exhibits intense blue emission at ambient temperature (Φ298 K = 0.44, λmax = 424 nm) in the crystalline state, while phenolate 2, another pyridinolate analogue bearing the nitrogen atom at a different position on the pyridine ring 3, and N‐phenylimidazolium ring 4 are less emissive (Φ298 K = 0.05, 0.05, and 0.04) under the same measurement conditions. Temperature‐dependent emission spectra indicate that crystal 1 exhibits high heat‐resistance properties towards emission decay and redshifting thermochromism upon increasing temperature, both of which are in contrast with the heat quenching and blueshift properties of phenolate analogue crystal 2 under the same measurement conditions. XRD analysis and DFT calculations revealed that the effect of the 2‐pyridinolate functionality on the specific efficiency and thermochromism in the crystalline‐state fluorescence of imidazolium arenolates arises from specific restriction of molecular rotation and the resultant molecular constraints in the crystals.

Under strongly basic conditions (f-BuO-/f-BuOD at 185 "C), the 9,9-dirnethyltricycl0[5.2.1.0~~~]-and -[5.2.1.0'*5]decan-8-ones and the homologous [5.3.1.0]undecanones undergo multi-site 'H/'H exchange. The total 2H uptake was monitored by mass spectrometry, while the individual sites of exchange were established by 13C NMR spectroscopy. The relative rates and stereoselectivity of incorporation at each site were determined by 'H NMR. These results extend our knowledge on the activating effect of the carbonyl group for proton abstraction at remote centres and are compared with earlier data for several related bi-and tricyclic systems. In addition, the 13C spectra provide several examples of geminal 2nd vicinat *H-induced isotope shifts in tricyclic carbon skeletons.
