Several cationic beta-vinyl-pyridinium and beta-vinyl-quinolinium-meso- tetraphenylporphyrin derivatives were synthesized starting from 2-formyl-meso-tetraphenylporphyrin, and the corresponding Zn(II) complex, and different N-alkyl derivatives of 2- and 4-methylpyridine and 2- and 4-methylquinoline. The new compounds were obtained in a one-step process via base catalyzed aldol-type condensation reactions. Electrospray ionization mass spectrometry (ESI-MS) and ultraviolet-visible (UV-vis) spectroscopy were used to investigate the binding mode of the synthesized cationic beta-vinyl-pyridinium and beta-vinyl-quinolinium-meso-tetraphenylporphyrin derivatives with a short GC duplex oligonucleotide. Analysis of the obtained mass spectrometry results indicates the probable occurrence of outside binding. UV-vis spectroscopy data also points to non-intercalation. The potential photosensitizing capacity of these compounds was also ascertained from preliminary photophysical studies.
