The balance between closed and open forms of spiropyrans in the solid state
Christer B. Aakeröy, Evan P. Hurley, John Desper, Manuel Natali, Antoin Douglawi and Silvia Giordani
We present three new crystal structures of members from the photochromic spiropyran family, including a rare example of an open (merocyanine) form. The molecular structures are systematically compared with existing crystallographically relevant data, and a new avenue for stabilizing open spiropyran forms in the solid-state is postulated.
