We report the synthesis of new mono, di and tri phosphonium ionicliquids and the evaluation of their antibacterial activities on both Gram-positive and Gram-negative bacteria from the ESKAPE-group. Among the molecules synthesized some of them reveal a strong bactericidal activity (MIC = 0.5 mg/L) for Gram-positive bacteria (including resistant strains) comparable to that of standard antibiotics.

A process for the preparation of the tertiary arylamine compound, comprising reacting and arylhalide, such as am arylbromide, and an arylamine in an ionic liquid in the presence of a catalyst.

The synthesis, one- and two-photonabsorption (2PA) and emission properties of two novel pyrrole-based conjugatedpolymers (P1 and P2) are reported. They emitted strong yellow-green and orange fluorescence with fluorescent quantum yields (Φ) of 46 and 33%, respectively. Their maximal 2PA cross sections (δ) measured by the two-photon-induced fluorescence method using femtosecond laser pulses in THF
