title: Synthesis of asymmetrically substituted 1,4,7,10-tetraazacyclododecanes for the triggered near infrared emission from lanthanide complexes.
abstract: A synthetic strategy to prepare asymmetrically substituted 1,4,7,10-tetrazadodecane derivatives was developed to prepare a novel series of photoactive donor-acceptor quencher triads based on Yb and Nd complexes; a nucleoside quencher is used to regulate the extent of energy transfer between the donor and the acceptor.
