Abstract :
A solvent-free, solid-phase one-step reaction between tetra-tert-butylated oxotitanium(IV) phthalocyanine and tetraazaporphyrin with 2,3,6,7,10,11-hexahydroxytriphenylene yields novel azaporphyrin cyclic trimers with triangular prismatic orientations. The fluorescence arising from the phthalocyanine and tetraazaporphyrin chromophores is significantly quenched upon trimerization.
