A photochromic carbazolyl-imidazolyl radical complex

A carbazole-incorporated photochromic radical complex is synthesized. The long-wavelength photosensitivity of the photochromic reaction of the molecule is enhanced up to similar to 580 nm by substituting a triphenylamine group into the 3-position of the carbazole moiety. These photochromic reactions are investigated by subpicosecond-to-microsecond transient absorption measurements.

Automated summary

A carbazole-incorporated photochromic radical complex is synthesized, and the long-wavelength photosensitivity of the molecule is enhanced up to around 580 nm by substituting a triphenylamine group at the 3-position of the carbazole moiety. The photochromic reactions are investigated using subpicosecond-to-microsecond transient absorption measurements.
