Quantum Yield Values for the Decomposition of Several Surface‐active Photoreactive Amphiphiles

Abstract

The quantum yield values for the decomposition of 12-azido-1-diazo-2-dodecanone, 1-diazo-11-dodecanone, 1-diazo-17-octadecen-2-one, stearoyl azide and 10-undecenyl azidoformate in hexane were determined. It was found that the compounds decomposed with relatively high quantum yields, suggesting their use in biological applications, especially for binding phospholipids to membrane proteins.

Comparison of the photochemical behavior of four different photoactivatable probes

“…Hence, each photocrosslinking experiment requires a careful selection of the appropriate photolabel depending on the nature and the structure-affinity relationships of the ligand. Up to now there have been only a few studies (12,(17)(18)(19), which compare photoprobes under identical conditions in order 'to facilitate the choice of the appropriate label. We chose for our studies four members of the most widely used photoactivatable compounds ( Fig.…”
