摘要：

We synthesized a series of novel thienyl-BODIPY monomers and oligomers as strong far-red to near-infrared (NIR) fluorophores. A 2,5-thienylene linker to connect the 3,5-positions of the BODIPY core realized the effective extension of the pi-conjugation and NIR absorption/emission property. Furthermore, it was found that rotatable substituted phenyl groups at the meso-position hardly decreased the strong fluorescence of the 3,5-thienyl BODIPYs, which would contribute to the design strategy of NIR dyes for various applications.
