Abstract: Procedure for the synthesis of a cationic water-soluble Pd(II) complex with 9-diethylamino-5$H$-benzo[$a$]phenoxazin-5-one (Nile red) [PdEnNR]OAc (where En – is ethylenediamine, NR – is deprotonated Nile red, OAc – is outer-sphere acetate-ion) is developed. The positive solvatochromism of the luminescent properties of the Pd(II) complex has been established. The influence of DNA on the spectral-luminescent properties of [PdEnNR]OAc was studied. Intercalation of the complex into DNA in water was found.

Keywords: cyclometallated Pd(II) complex, Nile red, luminescence, intercalation of the Pd(II) complex in DNA.
