Photocleavages of double-stranded circular DNA and oligonucleotide were investigated by the use of phosphorus(V)tetraphenylporphyrin (P(V)TPP) derivatives. The P(V)TPP derivatives cleaved the DNA and the oligonucleotide under the visible light irradiation, in air and in argon, respectively. It is suggested that the photocleavage reactions include an electron transfer mechanism as well as a singlet oxygen (1O2) one.
利用磷(V)四苯基卟啉(P(V)TPP)衍生物研究了双链环状DNA和寡核苷酸的光裂解。P(V)TPP衍生物分别在可见光照射下、空气中和氩气中裂解DNA和寡核苷酸。研究表明,光裂解反应包括电子转移机制和单线态氧(1O2)机制。
