【摘要】 吩噻嗪与蒽之间可以发生光诱导单电子转移反应.用荧光光谱仪研究了十二烷基硫酸钠（SDS）/苯甲醇（BA）/水微乳液中吩噻对对蒽的荧光猝灭.结果表明,在W/O微乳液中,蒽位于苯甲醇连续相,吩噻嗪位于膜相,猝灭反应发生于膜相;而在O/W微乳液中,蒽既可位于油核中,也可位于膜相,吩噻嗪位于膜相,猝灭反应亦发生于膜相.更多还原

【Abstract】 Photoinduced electron transfer reaction of anthracene with phenothiazine(PTZ) occurs in the membrane phase of the SDS(sodium dodecyl sulfate)/benzyl alcohol/H2O microemulsion. PTZ exists in the membrane phase because the rate for the photoinduced reaction between CHCU and PTZ in microemulsion is much slower than that in BA. Anthracene locates in the membrane phase or the oil core of the O/W microemulsion and in the oil continuous phase of the W/O microemulsion. The quenching of the excited anthracene by PTZ occurs in the membrane phase either for the W/O microemulsion or for the O/W microemulsion.更多还原
