Abstract

Abstract:

In this article, a bis-ureidopyrimidinone-containing iodinated Bodipy (I-Bodipy-BisUPy) has been designed and synthesized through an efficient thiol-yne click reaction. I-Bodipy-BisUPy has been characterized by ¹HNMR and HR-MS. The quadruple hydrogen bonding would drive the formation of supramolecular polymer, which is indicated by ¹HNMR of I-Bodipy-BisUPy in CDCl₃. The photophysical properties of I-Bodipy-BisUPy have been thoroughly investigated by examining the steady-state UV-Vis absorption and emissions spectra, nanosecond time-resolved transient absorption spectra, and low temperature phosphorescence spectrum. Water-dispersible nanoparticles of supramolecular polymer from I-Bodipy-BisUPy was prepared using the miniemulsion method. ESR and efficient photo-oxidation of 1,5-dihydroxynaphthalene justified that singlet oxygen (¹O₂) could be produced by the supramolecular polymer nanoparticles and employed for the photosensitive oxidation in water.

Key words: Bodipy, supramolecular polymer, quadruple hydrogen bonds, nanoparticles, photooxidation
