WebApr 10, 2013 · Photolysis of regioisomeric helical chromenes 1 and 2 leads to colored reactive intermediates. While the latter generally decay quite rapidly, they are found to be longer lived in 1 and highly persistent in 2. The remarkable stability of the otherwise fleeting transient in 2 allowed isolation and structural characterization by X-ray crystallography. … WebFurthermore, the optical chirality-CD was also modulated by UV irradiation. According to the TEM images and dynamic light scattering data, the photoswitching process involves...
