H. Tanaka et al., TETRA(TERT-BUTYL)PHTHALOCYANINE COPPER-IODINE COMPLEX FILM WITH LARGEDICHROISM INDUCED BY SHEAR, Journal of the Chemical Society, Chemical Communications, (16), 1994, pp. 1851-1852
A unidirectional arrangement of phthalocyanine molecules at a 'materia
l level' is achieved by shearing phthalocyanine-iodine complex, giving
a new dichroic phthalocyanine film.
