| 摘 要： | 2-(4-Pyridyl)imino nitroxide and tetraphenylporphyrin zinc(Ⅱ) formed a stable complex by noncovalent bonding in a nonpolar solution.Nicotine displaced 2-(4-pyridyl)imino nitroxide when it was added to a solution of 2-(4-pyridyl)imino nitrox-ide-tetraphenylporphyrin zinc(Ⅱ).The fluorescence intensity of tetraphenylporphyrin zinc(Ⅱ) was altered by sequentially addition of 2-(4-pyridyl)imino nitroxide and nicotine.This was used to develop a new method for detection of nicotine.

| Abstract: | 2-(4-Pyridyl)imino nitroxide and tetraphenylporphyrin zinc(II) formed a stable complex by noncovalent bonding in a nonpolar
solution. Nicotine displaced 2-(4-pyridyl)imino nitroxide when it was added to a solution of 2-(4-pyridyl)imino nitroxide-tetraphenylporphyrin
zinc(II). The fluorescence intensity of tetraphenylporphyrin zinc(II) was altered by sequentially addition of 2-(4-pyridyl)imino
nitroxide and nicotine. This was used to develop a new method for detection of nicotine. |
