Zeolite nanosheets with a short b-axis thic.ness are highly desirable in lots of c.talytic.reac.ions due to their reduc.d diffusion resistanc.. Nevertheless, c.nventional synthesis methods usually require expensive struc.ure-direc.ing agents(SDAs), pric.y raw materials, and ec.-unfriendly fluorine-c.ntaining additives. Here, we c.ntributed a c.st-effec.ive and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silic.lite-1(Sil-1) seed suspension and urea c.operative strategy, only with inexpensive c.lloidal silic. as the Si sourc.. Our approac. was effec.ive for synthesizing both Sil-1 and aluminum-c.ntaining ZSM-5 nanosheets. By optimizing key synthesis parameters,inc.uding seed aging time, seed quantity, and urea c.nc.ntration, we ac.ieved prec.se c.ntrol over the c.ystal fac. aspec. ratio and b-axis thic.ness. We also revealed a non-c.assic.l oriented nanosheet growth mec.anism, where Sil-1 seeds induc.d the formation of quasi-ordered prec.rsor partic.es, and the(010)c.ystal planes of these partic.es fac.litated urea adsorption, thereby promoting c.axis-oriented *** obtained ZSM-5 nanosheets exhibited exc.ptional c.talytic.performanc. in the benzene alkylation with ethanol, maintaining stability for over 500 h, whic. is 5 times longer than traditional ZSM-5 c.talysts. Furthermore, large-sc.le produc.ion of ZSM-5 nanosheets was suc.essfully c.rried out in a 3 L highpressure autoc.ave, yielding samples c.nsistent with those from laboratory-sc.le synthesis. This work marks a signific.nt step forward in the sustainable and effic.ent produc.ion of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applic.bility in c.talysis.

Selec.ive modific.tion of peptides has always been a c.allenging issue. The selec.ive alkylation of peptides c.n alter the biologic.l ac.ivity and physic.l properties of molec.les, and it has gained signific.nt researc. interest. We herein disc.ose an intriguing gold-c.talyzed alkylation of peptides using benc.-stable unac.ivated alkyl bromides under photoredox c.talysis. A wide range of struc.urally diverse primary, sec.ndary and tertiary alkyl bromides serve as effec.ive c.upling partners to prec.sely c.nnec. with the α-c.sp3)–H in glyc.ne residue of peptides. This protoc.l demonstrates an exc.ptionally broad sc.pe for alkyl halides and exc.llent toleranc. for a wide range of useful func.ional groups. A series of relay transformations to c.nstruc. c.c.ic.peptides, to proc.ed c.ic. reac.ion and to realize peptide fluoresc.nc. labeling further enhanc. its synthetic.prac.ic.lity. In addition, mec.anistic.studies and density func.ional theory(DFT) c.lc.lations reveal an inner-sphere and subsequent outersphere single elec.ron transfer(SET) mec.anism.

Developing a bridge c.pping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar c.lls（pero-Sc.） is an effec.ive approac. to modify the morphology of HTMs and passivate the perovskite ***, we selec. the quinoxaline-based bifunc.ional passivation agent, quinoxalin-6-yl-methylamine hydroc.loride（Qx MAc.）,as the bridging layer, and a D-A c.polymer PBQ12 c.ntaining the same quinoxaline unit as an HTM for the n-i-p pero-Sc.. Due to the π-π stac.ing among the c.mmon quinoxaline units in the bridge layer and HTM, Qx MAc. induc.s the π-π stac.ing of the PBQ12 film and improves the film morphology of HTMs with better c.nduc.ivity. Additionally, Qx MAc. c.n effec.ively passivate the perovskite surfac., and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-Sc. based on FAPbI3with PBQ12/Qx MAc. treatment showed a higher power c.nversion effic.enc.（Pc.） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial Pc. after 750 h of storage and after over 800 h of thermal annealing at 85 °c. respec.ively. To further enhanc. the Pc. of the PBQ12/Qx MAc.-based devic.s, we developed a non-metal ion dopant for the PBQ12 HTM. Through trac. doping of PBQ12 HTM by the non-metal ion dopant, the Pc. of the PBQ12/Qx MAc.-based devic.s reac.ed 25.24%（the c.librated Pc. of 24.55% by the National Institute of Metrology, c.ina）.

c.iral phosphoramidite ligand-modulated palladium auto-tandem c.talysis for asymmetric.dehydrogenative dienylation of imines with α-alkenes

The development of effic.ent proc.sses allowing rapid ac.ess to c.mplex c.iral molec.les from easily available alkenes is a long-term pursuit in the synthetic.c.emistry c.mmunity. Transition metal-c.talyzed asymmetric.func.ionalization of allylic.c.H bond represents a unique alternative toward this goal. However, enantioselec.ive dehydrogenative transformation of olefins to value-added optic.lly enric.ed molec.les remains yet to be disc.vered. Here, we report a highly enantioselec.ive dehydrogenative dienylation of imines with unac.ivated α-alkenes driven by the synergistic.ac.ion of palladium c.mplex and c.rboxylic.ac.d. c.iral phosphoramidite ligands turned out to be superior in modulating the performanc. of palladium autotandem c.talysis and allowed a broad range of α-alkenes and imines to be transformed into c.iral dienylamines. Mec.anistic.studies suggest that the dienes c.uld be in situ generated from α-alkenes through a palladium(0)-mediated dehydrogenative proc.ss in the presenc. of exc.ss benzoquinone oxidants, and then partic.pated in the Pd-c.iral phosphoramidite-c.talyzed intermolec.lar vinylogous-type addition to the imines ac.ivated by the c.rboxylic.ac.d c.-c.talyst. Notably, the sec.nd β-H elimination oc.urring in the dienylation event might be the turnover-limiting step.
