We report the synthesis and characterization of poly(3-decylselenylene vinylene) (P3DSV) homopolymers and poly(3-decylselenylene vinylene)--poly(3-decylthienylene vinylene) (P3DSV--P3DTV) copolymers through acyclic diene metathesis (ADMET) polymerization techniques. The obtained polymers were fully characterized. P3DSV was found to possess reduced crystallinity and a smaller bandgap of about 1.6 eV, compared with those of poly(3-decylthienylene vinylene) (P3DTV) analogs. P3DSV--P3DTV shows electronic properties between those of the corresponding homopolymers and distinctly different from those of simple blends of the two homopolymers. Our methodology provides a new way to control the physical and electronic properties of low bandgap poly(arylene vinylene)s (PAVs).
我们报道了通过开环二烯复分解（ADMET）聚合技术合成并表征聚（3-癸基亚硒基乙烯撑）（P3DSV）均聚物以及聚（3-癸基亚硒基乙烯撑）-聚（3-癸基噻吩基乙烯撑）（P3DSV-P3DTV）共聚物的过程。对所获得的聚合物进行了全面表征。结果发现，与聚（3-癸基噻吩基乙烯撑）（P3DTV）类似物相比，P3DSV的结晶度降低，带隙约为1.6 eV，更小。P3DSV-P3DTV的电子性质介于相应均聚物之间，且明显不同于两种均聚物的简单共混物。我们的方法为控制低带隙聚（亚芳基乙烯撑）（PAV）的物理和电子性质提供了一种新途径。
