Effect of acetylene linkage on solvatochromism of betaine consisting of 1-methylpyridinium and phenolate units

Solvatochromic behavior of 4-[2-(1-methylpyridinium-4-yl)ethynyl]phenolate (5) in various solvents was investigated to elucidate the effect of C≡C linkage. 5 was found to exhibit negative solvatochromism, where the observed maximum absorption wavelengths were short in polar solvents. Plots of the ab...
