Gold clusters loaded on various supports have been widely used in the fields of energy and biology. However, poor photostability Au support interfaces under prolonged illumination usually results loss catalytic performance. Covalent organic frameworks (COFs) with periodic ultrasmall pore structures are ideal for dispersing stabilizing clusters, although it is difficult to encapsulate pores. In this study, a two-dimensional (2D) COF modified thiol chains its pores was prepared. With -SH...

Thermally conductive materials (TCMs) are highly desirable for thermal management applications to tackle the "overheating" concerns in electronics industry. Despite recent progress, development of high performance TCMs integrated with an in-plane conductivity (TC) higher than 50.0 W (m K)-1 and a through-plane TC greater 10.0 is still challenging. Herein, self-standing liquid metal@boron nitride (LM@BN) bulks ultrahigh were reported first time. In LM@BN bulks, LM could serve as bonding...

Abstract By a facile peripheral decoration of 5‐(4‐aminophenyl)‐10,15,20‐triphenylporphyrin (ATPP) with inherent aggregation‐induced emission (AIE) active tetraphenylethene (TPE), versatile AIEgenic porphyrin derivative (ATPP‐TPE) was obtained, which greatly abolishes the detrimental π–π stacking and thus surmounts notorious aggregation‐caused quenching (ACQ) effect ATPP in aqueous phase. The photoluminescence ATPP‐TPE is 4.5‐fold stronger than at aggregation state. Moreover, an unequivocal...
