Design and synthesis of new fluorophores with emission in the second near‐infrared window (NIR‐II, 1000–1700 nm) have fueled the advancement of in vivo fluorescence imaging. Organic NIR‐II probes particularly attract tremendous attention due to excellent stability and biocompatibility, which facilitate clinical translation. However, reported organic NIR‐II fluorescent agents often suffer from low...
In article number 1805549, Xiaowei Chen, Jie Liu, Hua Feng, and co‐workers prepare a new aggregation‐induced emission (AIE) luminogen (AIEgen) through molecular engineering by varying a single atom from sulfur to selenium. The resultant AIE nanoparticles have an emission tail extending to 1200 nm with a high quantum yield. The light from these nanoparticles allow for clear vessel imaging.
As conjugated polymer nanoparticles (CPNs) have attracted growing interest as photoacoustic (PA) imaging contrast agents, revelation of the relationship between the molecular structure of conjugated polymers and PA property is highly in demand. Here, three donor–acceptor‐structured conjugated polymer analogs are designed, where only a single heteroatom of acceptor units changes from oxygen to sulfur...
Remarkable progress has been made in developing high performance organic field‐effect transistors (OFETs) and the mobility of OFETs has been approaching the values of polycrystalline silicon, meeting the requirements of various electronic applications from electronic papers to integrated circuits. In this review, the key points for development of high mobility OFETs are highlighted from aspects of...
