In addition of the piezochromic and the photochromic (dimer A) dimers of 2,4,5-triphenylimidazolyl, two new isomeric dimers were prepared; one (dimer B) being photochromic and the other (dimer C) non-photochromic. Several <I>p</I>-substituted derivatives of the dimers were also prepared. By comparison of their NMR and IR spectra, structures (a), (b), and (c) were assigned to the dimers A, B, and C, respectively. On treatment with hydrochloric acid in ethanol, dimer A underwent heterolytic cleavage and gave a mixture of 2-ethoxy-2<I>H</I>- and 4-ethoxy-4<I>H</I>-2,4,5-triphenylisoimidazole, and 2,4,5-triphenylimidazole.
