  The invention relates to new compounds of formula (1) wherein R is hydrogen or a linear or branched C 1-40 alkyl; where X is O, S, or NR 1 where R 1 is a hydrogen, a linear or branched C 1-40 alkyl, C 2-40 alkenyl or C 2-40 alkynyl group, an aryl, a heteroaryl or C 1-40 alkylaryl or alkylheteroaryl group and where one or both of C and D is OR 2 , SR 2 , NR 3 R 4 where R 2 , R 3 and R 4 are each independently hydrogen, a linear or branched C 1-40 alkyl, C 2-40 alkenyl or C 2-40 alkynyl group, an aryl or C 1-40 alkylaryl group or a linear or branched C 1-40 alkyl NR 5 R 6 chain where R 5 and R 6 are each independently hydrogen, a linear or branched C 1-40 alkyl; or an optionally complex metal ion M n+ /n wherein n is an integer from 1 to 8; or where one or both of C and D are amino acids or nucleic acids attached via either N, O or S; and wherein m is an integer from 1 to 8; and wherein either: I) A is a known aryl or heteroaryl fluorescent group and B is hydrogen, a linear or branched C 1-40 alkyl, C 2-40 alkenyl or C 2 4 alkynyl group, an aryl, a heteroaryl or C 1-40 alkylaryl or alkylheteroaryl group or phosphonate P(O)(OR 2 ) 2 ; II) B is a known aryl or heteroaryl fluorescent group and A is hydrogen, a linear or branched C 1-40 alkyl, C 2-40 alkenyl or C 2-40 alkynyl group, an aryl, a heteroaryl or C 1-40 alkylaryl or alkylheteroaryl group or a linear or branched C 1-40 alkyl NR 5 R 6 chain, or a linear or branched C 1-40 alkyl mono or di ester C 1-40 alkylphosphonate or a linear or branched C 1-40 alkylphosphonic acid; III) Both A and B are known aryl or heteroaryl fluorescent groups. The compounds are useful as fluorescent sensors for metal cations and have the advantages of excellent water solubility, selectivity and sensitivity to a variety of metal cations even in the presence of high concentrations of Ca +2 Na + and K + , good cell permeability, flexible and simple syntheses, ease of attachment to polymers and bio-polymers to aid the identification of both chemical and biological processes as well as for assaying physiological samples and for the attachment to surfaces such as glasses, ceramics and apatites.
