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.2-（4-Pyridyl）imino nitroxide and tetraphenylporphyrin zinc（II） formed a stable complex by noncovalent bonding in a nonpolar solution.
