The present invention relates to phosphoric acid/phosphonic acid derivatives shown by formula (I), wherein, R
1
or R
2
represents the following structures: (Q1), or (Q2), or (Q3). Q1 represents ester derivatives of L-amino acid, wherein R
3
is alkyl with 1-6 carbon atoms or cycloalkyl, R
4
is H or alkyl with 1-6 carbon atoms; Q2 represents hydroxyl substituted benzodioxane derivatives; Q3 represents hydroxyl substituted benzodioxolane derivatives; R
1
or R
2
is the same or different, but at least one of them is Q2 or Q3; D represents residues of pharmacologically active molecules containing a phosphate/phosphonate group, i.e. formula (II) represents pharmacologically active molecules containing a phosphate/phosphonate group; and when R
1
and R
2
are different, the configuration of the P atom connected to R
1
and R
2
is of R or S type.
