Abstract
The design and characterization of amorphous alternating copolymers endowed with a satisfactory thermal stability are reported. These alternating poly(CTFE- alt -CEVE) copolymers are synthesized by radical copolymerization of chlorotrifl uoroethylene (CTFE) with 2-chloroethyl vinyl ether (CEVE), which are fi rst modifi ed into poly[CTFE- alt -(2-iodoethyl vinyl ether)] copolymers and then azidated in high yields. Alkynyl CF 3 -containing phthalocyanines (Pcs) are then grafted via a copper-catalyzed Huisgen dipolar 1,3-addition ("grafting onto"), hence providing fl uorinated copolymers with different degrees of grafting (from 10 to 72%) of Pc dangling groups. Electronic spectral (absorption, excitation, and fl uorescence) and photophysical properties (fl uorescence lifetimes, τ F , and quantum yields, Φ F ) are evaluated.
