library of 2,5-furan-based phenylene/thiophene oligomers were synthesized starting from 5-bromofurfural, a derivative of biomass-derived furfural. Varied electronic groups are coupled onto the furan motif, followed by the installation of a phenylene or thiophene central linker through a one-pot Pd-catalyzed decarboxylative cross-coupling reaction. Resulting oligomers containing the furan-phenylene-furan
以 5-溴糠醛(一种生物质衍生的糠醛衍生物)为原料,合成了基于 2,5-呋喃的亚苯基/噻吩低聚物库。将各种电子基团偶联到呋喃基序上,然后通过一锅钯催化的脱羧交叉偶联反应安装亚苯基或噻吩中心连接基。所得含有呋喃-亚苯基-呋喃核心的低聚物在溶液中具有高光致发光量子产率(83-98%),这对于光电器件至关重要。通过改变外围官能团和耦合到呋喃骨架上的中心连接体来调节吸光度和光致发光最大值。
