摘要：
The 1,8-diaminonaphthalene has various optical applications and electropolymerisation characteristics. The interaction of 1,8-diaminonaphthalene with p-sulfonatocalix[4]arene is studied using absorption, emission, excited state lifetime, and electrochemical techniques. The binding constant values calculated from these techniques are around 102–105 M−1, which emphasizes the efficient binding of 1,8-diaminonaphthalene with p-sulfonatocalix[4]arene. The excited state lifetime is enhanced in the presence of p-sulfonatocalix[4]arene and the propensity of polymerization of 1,8-diaminonaphthalene under electrical environment is inhibited in the presence of p-sulfonatocalix[4]arene. The structure and the mode of binding between 1,8-diaminonaphthalene with p-sulfonatocalix[4]arene complex is studied using 1H NMR and rotating frame overhauser effect spectroscopy (ROESY) techniques.
