•Subphthalocyanine-substituted hexameric and octameric cyclic phosphazenes.•Photophysical properties of the compounds in 1,4-dioxane.•Ground state electronic absorption and fluorescence spectra.•Fluorescence quenching by 1,4-benzoquinone.
Hexameric and octameric subphthalocyanines bearing cyclophosphazene derivatives were synthesized by threating hexa(p-hydroxyphenoxy)cyclotriphosphazene and octa(p-hydroxyphenoxy)cyclotetraphosphazene with excess of boron subphthalocyanine chloride in toluene. The hexameric and octameric subphthalocyanines bearing cyclophosphazene derivatives were fully characterized by elemental analysis, ESI and MALDI mass spectrometry, FT-IR, 1H, 13C and 31P NMR spectroscopy. The photophysical properties of title compounds were investigated by means of UV/Vis absorption and fluorescence spectroscopies in dilute 1,4-dioxane solutions. The fluorescence quenching behavior of these complexes by 1,4-benzoquinone were also reported.
