The title compound, C29H23F6NO2S, a member of a new family of photochromic diarylethene compounds having an unsymmetrically substituted hexafluorocyclopentene unit, displays dihedral angles between the indole and thiophene rings of 52.5 (4)°, and between the indole ring and the planar C—C=C—C unit of the cyclopentene ring of 53.8 (6)°. The distance between the potentially reactive C atoms from the two heteroaryl substituents of 3.817 (6) Å is proven to be short enough for photocyclization to occur.

To a tetrahydrofuran solution of 1,2-dimethyl-3-bromoindole (1.12 g, 5 mmol) was added a hexane solution of n-butyl lithium 2.5 M (2.0 ml, 5 mmol) at 195 K under a nitrogen atmosphere. The mixture was stirred for half an hour. An excess of octafluorocyclopentene (1.5 ml, 10 mmol) was added and stirring was continued for another 2 h at this temperature. The reaction was then quenched by the addition of water. The product, 1,3,3,4,4,5,5-heptafluoro- 2-(1,2-dimethyl-3-indolyl)-3,3,4,4,5,5-hexafluorocyclopent-1-ene (0.76 g, 2.25 mmol), was collected and dried (yield 45.0%). This compound (0.76 g, 2.25 mmol) was reacted with 3-bromo-5-(3-(2,5-dioxolanyl)phenyl)-2-methylthiophene (0.73 g, 2.25 mmol; Irie et al., 2003) in the presence of n-butyl lithium 2.5 M (0.90 ml, 2.25 mmol) at 195 K under a nitrogen atmosphere. After an hour, the reaction was quenched by the addition of water. The solid product was purified by
on silica using petroleum ether as the eluant to give the title compound (yield 0.47 g, 0.83 mmol, 37.0%).Crystals suitable for analysis were obtained by slow evaporation of a solution in hexane. Analysis: calculated for C29H13F6NO2S:C 61.81, H 4.11%; found C 61.84, H 4.20%.All H atoms were placed in calculated positions with C—H equal 0.93 Å for aromatic and 0.96 Å for CH3 groups. They were included in the
in the riding model approximation with isotropic displacement parameters set equal to 1.2Ueq(C) and 1.5Ueq(C) of the for the aromatic and methyl H atoms, respectively.Data collection: SMART (Bruker, 1997); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound when dissolved in hexane shows photochromism. Upon irradiation with 297 nm light, the colorless hexane solution turns blue rapidly. The blue compound displays an absorption maximum at 592 nm. Upon irradiation with visible light with wavelength longer than 510 nm, the blue hexane solution reverts to its initial colorless state; a colorless hexane solution of the title compound has an absorption maximum at 278 nm. In a polymethylmethacrylate amorphous film, the title diarylethene also exhibits photochromism similar to that in hexane.
