Abstract
Universal cyclic scaffolds of acrylate polymers with pentafluorophenyl active ester groups were synthesized using the α, ω- ring closing method and confirmed with a variety of characterization techniques. The incorporation of the active ester into the universal scaffold allows for alteration of the side groups by post polymerization modification. The preparation of this universal cyclic scaffold lays the synthetic foundation for materials that take advantage of cyclic polymer properties. Prerequisite linear poly(pentafluorophenyl methacrylate) was prepared possessing well-defined photoactive end groups and the conditions for the hetero Diels-Alder ring closing reaction were optimized.
The synthesis of a series of phenanthridine and quinolone based fluorophores was explored for post polymerization modification. A series of linear and cyclic polymers with active esters were substituted to comparable degrees with a phenanthridine-based fluorophore and of the two topologies the cyclic polymers exhibited the expected enhanced emissivity.
