“…[10][11][12][13][14][15][16][17] Disruption of conjugation by incorporating functionalities that twist the p-system from coplanarity is one strategy that facilitates exciton confinement. [15] Another strategy towards tuning CP photophysical profiles is to prepare hyperbranched luminescent polymers that bear functionalities that allow them to be functionalized post-polymerization, [18] thus affording a remarkable platform for tailored application and property acquisition.…”

Two poly(p-phenylenevinylene) derivative alternating copolymers (P1-I and P2-I) have been prepared featuring iodo substituents and m-phenylene units to periodically disrupt conjugation. P1-I was derivatized with various chromophores to yield P1a-f. In P1a-f, the chromophores were positioned within a sterically protected pocket shielding them from interchain interactions so that intrachain interactions between polymer segments could be observed. Solution and film properties of polymers have been examined. Post-polymerization chromophore modification leads to new photophysical properties such as intramolecular charge transfer and fluorescent resonance energy transfer processes in some cases.

Fluorescent hyperbranched polymers (FHBPs), which combine the versatile fluorescent property with unique characteristics of hyperbranched architecture, are desirable candidates for stimulus responsive materials. This review demonstrates the structure and environment-dependent emission behaviors of a series of FHBPs. AEE active FHBPs showing opposite performance to ACQ effect are used to sensitively detect explosives and a superamplification effect is found. Specially designed FHBPs can complex with metal ions, leading to fluorescence turn-off due to complex quenching effect. The protonation of amino-containing FHBPs exhibits pH-dependent fluorescence responses to solution acidity. Some FHBPs containing responsive moieties are photo-and thermo-sensitive, and show potential applications as smart materials. fluorescent hyperbranched polymer, explosives and metal ions detection, pH responsive, optical and thermal sensitive
