wherein
R
1
is a group Ar
1
L
2
Ar
2
Alk- in which:
Ar
1
is an optionally substituted aromatic or heteroaromatic group;
L
2
is a covalent bond or a linker atom or group;
Ar
2
is an optionally substituted arylene or heteroarylene group;
and Alk is a chain
in which R is a carboxylic acid (—CO
2
H) or a derivative or biostere thereof;
X is an —O— or —S— atom or —N(R
2
)— group in which:
R
x
, R
y
and R
z
which may be the same or different is each a hydrogen atom or an optional substituent;
or R
z
is an atom or group as previously defined and R
