A novel organic conjugated polymer based on star-shaped triazine-functional triphenylamine framework poly[1,3,5-tris(4-diphenylamino-phenyl)triazine] (PTDAPTz) is designed and synthesized successfully by FeCl3-catalysted chemical oxidative polymerization. The polymer PTDAPTz powder exhibits a compactly packed pleated skirt shape-like morphology with a high surface area (similar to 930 m(2) g(-1)) and a bimodal pore size distribution ranging from micropores (similar to 0.55 nm) to small diameter mesopores (similar to 2-6 nm). As explored as the cathode material, the obtained PTDAPTz presents the double charge-discharge process characteristics of both the free radical redox of triphenylamine unit and the bipolar redox of triazine unit in the polymer and a well-defined multistage charge/discharge voltage plateau (similar to 3.8 V for p-doped and similar to 2.0 V for n-doped) during the charge-discharge process. Also, the PTDAPTz demonstrates an improved capacity (stabilized at 123 mA h g(-1) until 50th cycle) and the enhanced rate performance compared to polytriphenylamine (PTPAn). Specially, the discharge curve for the part of triphenylamine unit presents an obviously improved discharge plateau (similar to 3.8 V for PTDAPTz compared to similar to 3.6 V for PTPAn) due to the electron-withdrawing effect of the triazine unit to triphenylamine. The elaborate structural design and created micro-/mesoporous morphology with the double charge-discharge process make PTDAPTz a potential candidate as the performance-improved cathode of Li-organic battery.
