To develop education, the pioneer revolutionist Dr Sun Yat-Sen (also known as Zhongshan Sun) initiated the merger of several colleges and universities in Guangzhou, China, in February 1924, establishing the National Guangdong University. This institution was renamed the National Sun Yat-Sen University in August 1926 in honor of Dr Sun Yat-Sen, later also known as Zhongshan University and currently Sun Yat-Sen University (SYSU). Over the past century, SYSU has become a comprehensive research university driven by its motto “Study Extensively, Enquire Accurately, Reflect Carefully, Discriminate Clearly, and Practice Earnestly”. Inaugurated as the Department of Chemistry of the University in 1924, the current School of Chemistry at SYSU was established in 1994. Today, it comprises seven research institutes supported by world-class research faculty and state-of-the-art facilities.
Over the past decade, researchers from SYSU have published more than 400 articles in Chemical Science and Chemical Communications. To celebrate the 100th Anniversary of SYSU in 2024, the Royal Society of Chemistry has the pleasure of presenting this joint themed collection, bringing together 29 recent articles contributed by SYSU researchers, alumni and collaborators across diverse fields of chemistry.

They also synthesized another ferroelectric (Me_3_NCH_2_CH_2_Br)[GaBr_4_], exhibiting a piezoelectric coefficient of up to 331 pC N^−1^, and fabricated a composite piezoelectric sensor with a high power density (490 μW cm^−2^) enhanced by the synergistic combination of piezoelectric and triboelectric (https://doi.org/10.1039/D4SC05442C). Zhao-Ping Ni and colleagues reported two mononuclear iron(iii) complexes that demonstrate counterion dependence of their magnetic and fluorescence properties. They observed, for the first time, a synergistic effect between abrupt spin crossover and fluorescence in an iron(iii) complex (https://doi.org/10.1039/D4CC05036C).

Fei Xu et al. synthesized the Mo_2_C/MoS_2_ heterostructure on carbon paper (Mo_2_C/MoS_2_-CP), through rapid carbothermal shock in only two seconds, which exhibits superior intrinsic alkaline hydrogen-evolution-reaction activity and excellent stability for 100 h (https://doi.org/10.1039/D4CC03757J). Gangfeng Ouyang and colleagues developed novel oxygen-centred organic radicals with an impressive half-life of up to seven minutes in water, thus achieving highly efficient photocatalytic removal of organic pollutants even under an ultra-low light intensity of only 0.1 mW cm^−2^ (https://doi.org/10.1039/D4SC06339B).
Functional materials for application in devices
Dingshan Yu et al. developed novel membrane electrolytes with high ionic conductivity (3.3 × 10^−4^ S cm^−1^) and Li^+^ transference number (0.74), endowing solid LiFePO_4_//Li batteries with excellent cyclability over 1000 cycles at 60 °C. Their strategy surmounts the ionic conduction-interface stability trade-off and thin dimension-flexibility conflict (https://doi.org/10.1039/D4CC04550E). Dingcai Wu and coworkers designed a super-structured multifunctional molecular brush and developed an ultrathin polymer electrolyte showing a remarkable capacity retention of 83% for Li/LiFePO_4_ cells at 1C after 1000 cycles. The solid-state fuel cell with a high-loading LiNi_0.8_Mn_0.1_Co_0.1_O_2_ cathode, delivers a high discharge specific capacity of 204 mA h g^−1^ for more than 400 cycles at a high cut-off voltage of 4.5 V (https://doi.org/10.1039/D4SC04454A).

By employing chain elongation and halogen substitution strategies, Dai-Bin Kuang et al. synthesized low-melting-point metal halides and obtained stable glass scintillators. The resulting glass exhibits a photoluminescence quantum yield of 47.6% and an impressive resolution of 25 lp mm^−1^ in X-ray imaging, and remains transparent even after being heated at 90 °C for six weeks (https://doi.org/10.1039/D4SC04229H). By optimizing the energy level alignment between the perovskite layer and the adjacent contacts, Wu-Qiang Wu et al. have successfully developed n–p homojunction-based perovskite solar cells without an electron transport layer, achieving an improved efficiency of ca. 13% higher than the control counterpart (https://doi.org/10.1039/D4CC05174B). Using scanning tunnelling microscopy break junction techniques, Jinghong Li et al. investigated the single molecule electrode coupling mode based on azulene controlled interface charge distribution, providing a new strategy for designing switchable single-molecule devices (https://doi.org/10.1039/D4SC06614F). Mei Pan et al. discovered an unexpected organic host–guest afterglow system, which was initiated by a paper (cellulose)-matrix approach and benefited from an efficient Förster resonance energy transfer from the host to the guest, thanks to the suitable host–guest energy level match (https://doi.org/10.1039/D4SC04746J).
Biochemistry and nanodrugs
Liang Xu and colleagues integrated the host–guest recognition system into the core region of the 10–23 DNAzyme, and demonstrated that the function of DNAzyme could be reversibly and orthogonally controlled by utilizing cucurbit(7)uril and its competitive guests (https://doi.org/10.1039/D4CC05330C). Xiaogang Qu et al. identified a highly conserved and stable G-quadruplex (G4) in the STING promoter region, and further verify its function in transcriptional inhibition of STING using CRISPR technology to precisely target STING G4. Their findings may promote drug design for Alzheimer's disease (https://doi.org/10.1039/D4SC04453C). Jinsong Ren et al. constructed nanodrugs by structurally hybridizing an antioxidant defense pharmacological inhibitor and a co-nucleation precursor through the formation of carbon quantum dots. These nanodrugs exhibit dual-enhanced bioactivities, and they have a long body retention time and desirable biodistribution in living cells, enabling the elimination of melanoma cells at a very low injection dose (https://doi.org/10.1039/D4SC05280C).
