Abstract	Platinum-based anticancer drugs are common in chemotherapy, but problems such as systemic toxicity and acquired resistance of some tumors hamper their clinical applications and therapeutic efficacy. It is necessary to synthesize Pt-based drugs and explore strategies to reduce side effects and improve pharmacokinetic profiles. Photo-responsive chemotherapeutics have emerged as an alternative strategy against several cancers, as photoactivation offers spatial selectivity and fewer side effects. Here, we combine chemical synthesis and nanotechnology to create a multifunctional platinum drug delivery system based on the novel metal complex [Pt(ppy)(curc)] (ppy = deprotonated 2-phenylpyridine, curc = deprotonated curcumin)] embodying the naturally occurring bioactive molecule, curcumin. The ultrasonication method coupled with the layer-by-layer technology was employed to produce nanocolloids, which demonstrated a good biocompatibility, higher solubility in aqueous solution, stability, large drug loading, and good biological activity in comparison with the free drug.

Abstract	To investigate the factors influencing the luminescent properties of cycloplatinated complexes containing aryl and SMe2 ligands, a detailed study of the photophysical and structural properties of the complexes [Pt(p-MeC6H4)(ĈN)(SMe2)], (ĈN = benzo[h]quinolate (bzq), 1, or 2-phenylpyridinate (ppy), 2), was conducted in solution and solid state at different temperatures. Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) investigations were carried out on both the singlet (S0, ground) and triplet (T1, excited) states of these complexes for explanation of the electronic structures, absorption and emission spectra. In the solid state, these complexes display an intense phosphorescence emission which was red-shifted from 2 to 1 due to expansion of the π conjugated system in the cyclometalated bzq ligand. These complexes are strongly emissive at 77 K, giving emission peaks similar to those observed at ambient temperature. The complex 1 in deoxygenated CH2Cl2 solution (at low concentration) gave a phosphorescence band which was accompanied by a higher-energy fluorescence band (ascribed to 1LC transition, centered on bzq ligand), and these bands disappeared when a concentrated solution or glassy state (77 K) of the complex is used. On the basis of theoretical calculations, the HOMO level is a mixture of platinum center and ligand orbitals, while the LUMO level is predominantly ĈN ligand based. The lowest-lying excited state responsible for the phosphorescence emission (with a significantly long lifetime) originates from mixed 3ILCT/3MLCT with some 3L′LCT excited state and the emission is red shifted in comparison to the corresponding free cyclometalating ligand.
