Abstract

See full text

Photochromic tetrahydroindolizines (THIs) bearing dihydroisoquinoline derivatives as heterocyclic bases and central fluorene goups have been synthesized via different chemical and photochemical pathways. Three alternative pathways for the synthesis of the target photochromic THI-based pyridazinopyrrolo [1,2-b] isoquinolines via in situ trapping with hydrazine hydrate are also provided. High product yields are obtained using different Sonogashira-mediated coupling reactions provided herein. Low temperature multichannel UV-vis and flash photolysis techniques were used to detect the photochromic and kinetic properties of the synthesized system.
