摘要：

Three trans-syn-3, 3'-diaryl-2, 2'-biindenyl-idene-1, 1'-diones (2a-c) showed sharp photochromic phenomena in their crystalline forms. By exposure to sunlight, 2a-c were converted to stable biradicals (3a-c). Although N, N'-dimethyl indigo (6) has an almost planar structure, 6 in its 1:1 inclusion crystal with the host 1, 1, 6, 6-tetraphenyl-2, 4-hexadiyne-l, 6-diol (7) was found to have a twisted structure of dihedral angle 42.6° between the two rings. © 1992, Taylor & Francis Group, LLC.
