This Feature Article overviews a new class of π-conjugated materials – macrocyclic furans.
Using long oligofurans as synthetic building blocks has been found to enable the efficient synthesis of conjugated furan-based polymers through direct C–H arylation, which exhibit excellent antimicrobial activity.
We have synthesized new metal-free dyes (HB-1–8) containing bifuran/biphenyl derivatives for dye-sensitized solar cells. Dye HB-3 exhibited the highest efficiency among the eight investigated dyes, reaching 5.51% with a VOC value higher than N3.
The color tuning of benzobisoxazole-based OLEDs to achieve white emission with high brightness is reported.
The emission colors of high-performance MCLCPs with biomass-based bifuran and AIE-active cyanostilbene units can be tuned by the composition from blue to cyan, and then to green. Upon UV exposure, the thin film can undergo an emission color change.
