Abstract
Efficient, three-step synthesis of new heterocyclic system - 2H-bis([1,2,3]triazolo)[5,1-a:4',5'-c]isoquinolines was elaborated using simple synthetic strategy. The approach permits to prepare target compounds in high yields using readily available aryl hydrazines and o-alkynylbenzaldehydes as starting materials. Photophysical properties of the prepared heterocycles were studied to demonstrate that the prepared compounds are attractive blue emitting fluorophores exhibiting quantum yields up to 98 % and Stokes shifts up to 67 nm. A strong effect of the steric hindrance on the absorption and emission spectra was revealed.
