Abstract

A new series of bodipy-functionalized cyclotriphosphazene derivatives were designed and synthesized. The identities of all newly synthesized compounds were confirmed by using H-1, C-13, P-31 NMR spectroscopies. The photophysical properties of bodipy-functionalized cyclotriphosphazenes were investigated via absorption and fluorescense spectroscopies in dichloromethane. Singlet oxygen generation capacities of new compounds were also examined using the trap molecule 1,3-diphenylisobenzofuran. The targeted compounds showed high molar extinction coefficients in the NIR region and respectable singlet oxygen quantum yields when compared to that of methylene blue. The new bodipy-functionalized cyclotriphosphazenes are efficient photosensitizers to be potentially used for the singlet oxygen generation.
