Abstract/OtherAbstract:
The recruitment of DO3A derived lanthanide complexes by ligation to isophthalic acid and catechol modified gold surfaces, and the resulting sensitisation, is reported herein. Predictably pH dependent surface recruitment is associated with the expected fingerprint europium and terbium emission characteristics. The intensity of the lanthanide luminescence scales exponentially with spacer length, indicating a strong quenching interaction between the lanthanide and the gold surface. The switchable catechol oxidation state provides a means of electrochemically triggering the release of prior ligated complexes.
