The dipolar character of 1,8-naphthalimide together with polarization of the C-4-H and C-5-H donors has been utilized in receptor 1 to effectively bind chloride alongside triazole and phenylene units. The Cl- binding strength of 1 shows that the naphthalimide provides greater anion stabilization than an unactivated phenylene, and DFT calculations show that its collinear donor array can be a "urea-like" analog for CH center dot center dot center dot anion interactions.
