to a photoreactive state with C2-symmetry around the hexatriene reaction center. Temperature-dependent NMR studies and quantum chemical calculations indicated the contribution of intramolecular hydrogen-bonding between the central azaindole unit and the side thiazole units, which stabilizes the photoreactive C2-symmetric conformation and elevates the photoreactivity in both non-polar and polar solvents
