H. Ihmels et al., 11,12-bis(diethylaminomethyl)-9,10-dihydro-9,10-ethenoanthracene: A probe for the heavy atom effect in solid state photoreactions, TETRAHEDRON, 55(8), 1999, pp. 2171-2182
The photochemistry of title compound 2 and its hydrogen halide salts was in
vestigated in solution and in the solid state. In the solid state the halid
e ions were shown to cause a heavy atom effect that was not observed in sol
ution. The orientation of the halide ions towards the chromophore was deter
mined on the basis of the corresponding structures in the solid state as de
termined by X-ray crystallography. (C) 1999 Elsevier Science Ltd. All right
