PharmDr. Petr Zimcik, Ph.D. Doctoral Thesis: Study of recognition moieties of sensoric azaphthalocyanines Azaphthalocyanines (AzaPcs) are planar macrocyclic compounds with unique photophysical properties like absorption and emission over 650 nm and high quantum yields of fluorescence. Alkylamine substituted AzaPcs have been shown to undergo an ultrafast intramolecular charge transfer (ICT) which is responsible for efficient quenching of excited states (nonfluorescent OFF state). ICT occurs between donor (peripheral amine) and acceptor (macrocyclic core). Blocking of ICT leads to restoration of high fluorescence emission (fluorescent ON state) which is the competitive relaxation pathway. There are two known possible ways how to block ICT in AzaPcs sofar: By protonation of donor in pH sensitive AzaPc sensors or by coordination of metal cation into the recognition moiety resulting in cation sensitive AzaPc sensors. Above-mentioned properties predestinate AzaPcs to become new fluorescent sensors with good brightness and advantageous absorption and emission of red light deep...
