| Résumé : |
New photoinitiating systems composed of benzothiazolestyrylium dyes as chromophores and n-butyltriphenylborate anion as electron donor were prepared and characterised. Photoredox pairs consisting of hemicyanine dyes and organoborate salts may act as visible-light photoinitiators for the radical polymerisation of multifunctional acrylates. The efficiences of these photoinitiator systems are based on the free energy changes of an electron transfer from borate salt to the dye. Experimental results show that the photoinitiating ability of the photoredox pair tested strongly depends upon the reduction potential of hemicyanine dye, the oxidation potential of borate salt, and the structure of the dicationic dye. |
