Abstract:
1. A polymer substrate functionalized with a metal ion coordinating functionality of general formula (I) wherein n is 1, 2 or 3; each of a, b and c in each triazacycloalkane ring, independently of each other and independently of any other triazacycloalkane ring, is 1, 2 or 3; one or both hydrogen atoms of each —CH the hydrogen atom of each —NH— group in each triazacycloalkane ring, independently of each other and independently of any other triazacycloalkane ring, may optionally be substituted with a substituent; when n is 1, R is a bifunctional group, said bifunctional group optionally comprising one or more metal ion coordinating donor atoms; when n is 2 or 3, R is an (n+1)-functional group, said (n+1)-functional group optionally comprising one or more metal ion coordinating donor atoms; and X is a linker/spacer group.
