( 1-Alkyl-4-pyridiniomethyl)phosphonates bearing long alkyl-chains of even carbon numbers of 8 to 18 were prepared. They exhibited the characteristics of surface-active agents. Upon irradiation in alkaline aqueous media, the phosphonates underwent the C-P bond cleavage to give 1-alkyl-4-methylpyridinium phosphates and as a result the surface tension of the solution also changed. The two-fold increases of the quantum yields of the C-P bond cleavage were found at their critical micelle concentrations.
