Polymeric polyurethane nanofabrics doped by zinc tetraphenylporphyrin (ZnTPP) and/or zinc phthalocyanine (ZnPc) photosensitizers
were prepared by the electrospinning method and characterized by microscopic methods, steady-state and time-resolved fluorescence,
and absorption spectroscopy. Nanofabrics doped by both ZnTPP and ZnPc efficiently harvest visible light to generate triplet
states and singlet oxygen O2(1Δg) with a lifetime of about 15 μs in air atmosphere. The energy transfer between the excited singlet states of ZnTPP and ground
states of ZnPc is described in details. All nanofabrics have bactericidal surfaces and photooxidize inorganic and organic
substrates. ZnTPP and ZnPc in the polyurethane nanofabrics are less photostable than incorporated free-base tetraphenylporphyrin
(TPP). 相似文献
