The metalation of Br–ThPy–Br (Th: thiophene-2,5-diyl; Py: pyridine-2,5-diyl) and 2-iodo-5-bromopyrimidine with i-PrMgCl proceeds regioselectively. The cross-coupling polycondensation of regioselectively metalated intermediates gives head-to-tail π-conjugated poly(thiophene–pyridine) and polypyrimidine, respectively, and their packing structures in the solid state and optical data are discussed.
Br-ThPy-Br(Th:噻吩-2,5-二基;Py:吡啶-2,5-二基)和 2-碘-5-溴嘧啶与 i-PrMgCl 的金属化反应具有区域选择性。区域选择性金属化中间体的交叉偶联缩聚分别产生了头尾π共轭的聚(噻吩-吡啶)和聚嘧啶,并讨论了它们在固态中的堆积结构和光学数据。
