The calculated narrow (2.20 eV) HOMO—LUMO gap in diamine 1 is consistent with its experimentally observed absorption (526 nm).

Within the framework of the electrostatic potential for intermolecular complexation (EPIC) model, it was shown that the most energetically favorable is the non-covalent interaction of diclofenac with carboxymethylcellulose moieties in the hydrogel network. The kinetics for diclofenac release from the polymeric matrix in various biorelevant environments was investigated.
