Abstract

Silicon-inserted triazacorrole, its μ-oxo dimer, and tetrabenzotriazacorrole have been obtained by ring contraction when metal-free tetraazaporphyrin (TAP) and phthalocyanine (Pc), respectively, were reacted with trichlorohydrosilane (HSiCl3) in the presence of tributylamine in refluxing benzene. The triazacorrole has very sharp absorption at ca. 400nm, which is suitable for blue-laser applications.
