In this thesis, we did modifications of alkyl groups upon benzyl fluorophosphonate. In order to study the influence of alkyl length and steric effect on activity and selectivity of probes, we synthesized benzyl fluorophosphonate recognition heads with modifications including ethyl, butyl, octyl and cyclohexyl. By way of connecting different kinds of tag like azido group, biotin and rhodamine with recognition heads separately through a higher hydrophilic ethylene glycol derived linker, a series of benzyl fluorophosphonate probes were made up. And they will apply to various biological testing strategies.
