Photophysical properties of 4-(5-methylthiophen-2-yl)pyridinium-cyclic enolate betaine dyes tuned by control of twisted intramolecular transfer

In this paper, thienylpyridinium-cyclic enolate betaine (TPB) dyes were reported as unique skeletons of fluorescent donor-acceptor type molecules. TPB derivatives with five-membered cyclic enolates are coplanar because of the intramolecular hydrogen bond formation between the carbonyl oxygens of the...
