Abstract
A series of 5,7,9-substituted 2-azapyrenes were synthesized for the first time. The synthesis relies on Brønsted acid promoted benzannulation of alkyne precursors prepared by palladium-catalyzed cross-coupling reactions. The synthetic strategy is efficient and the scope covers a variety of functional groups. The electrochemical behavior and photophysical properties of the products were investigated by UV-vis and fluorescence spectroscopy, cyclic voltammetry, and DFT calculations.

Abstract
The N,N'-dimethyl-3,3'-biquinoxalinium "methylbiquinoxen" dicationic platform is revealed to have even more fascinating possibilities than we originally thought in terms of its chemical versatility. In addition to its rich redox chemistry and coordination abilities, we have now unveiled an unexpected Lewis acid/base chemistry linked with a tuneable switching of its luminescence properties. This, amongst other things, allows for the facile fluorescent covalent labelling of hydroxyl-terminated materials. This platform provides intriguing chemical prospects realised in molecular systems such as porphyrins as well as an easy alternative functionalisation methodology to that provided by click-chemistry.

Abstract
The interactions of 8-hydroxybenzo[b]quinolizinium and 9-hydroxybenzo[b]quinolizinium with DNA are investigated in detail. Specifically, spectrophotometric and spectrofluorimetric titrations, thermal DNA-denaturation experiments as well as CD- and LD-spectroscopic analysis show that a pH shift by just one or two orders of magnitude has a significant impact on the interactions of the acidic ligands with the nucleic acid. Both ligands bind with high affinity to DNA at pH 6 (Kb ≈105 m-1 ). At pH 7 or 8, however, the binding interactions are much weaker because of the formation of the corresponding charge-neutral conjugate bases, the affinity to DNA of which is reduced because of the resulting lack of a positive charge. Notably, the variation of DNA affinity occurs in a range that corresponds to the fluctuations of pH values under physiological conditions, so that these ligands may be employed to target DNA in tissue with particular pH values, especially, cancer cells. The antiproliferative activity of the title compounds under different conditions is also investigated. In the absence of irradiation, both compounds show only a modest cytotoxicity toward cancer cells. However, upon irradiation, even at low UV-A doses, a significant reduction of cell viability of tumor cell lines is induced by the ligands.

Abstract
The effect of the luminescent heteroaromatic electron acceptor N,N'-dimethyl-2,7-diazapyrenium dichloride (DM-DAP(2+)) on the stability of 1-palmitoyl-2-oleoylphosphatydilcholine (POPC) liposomes is determined on the basis of the rate of release of different fluorescent probes entrapped within the liposome. The experiments show that DM-DAP(2+) exerts a substantial destabilizing action on the liposomal bilayer, particularly at low concentrations. Molecular dynamics simulations suggest that the activity of DM-DAP(2+) is related to its tendency to surround itself with water molecules, conceivably favoring the formation of transient pores across the bilayer.
