合成了一种含咔唑的光致变色自由基配合物。通过在咔唑的3-位上引入三苯胺基团，使该分子的光致变色反应的长波长光敏性提高到λ 580 nm。这些光致变色反应进行了研究，通过亚皮秒到微秒的瞬态吸收测量。
A carbazole-incorporated photochromic radical complex is synthesized. The long-wavelength photosensitivity of the photochromic reaction of the molecule is enhanced up 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.
