英文摘要 | After the milestone discovery of the first single-molecule magnets(SMMs) Mn_(12)ac,many new SMMs were structurally and magnetically characterized.The most studied systems are mainly conventional coordination compounds with polynuclear structures.From 2011,we explored a series mononuclear organometallic sandwich molecules,Cp*LnCOT(Cp* = C_5Me_5~-,pentamethylcyclopenta-dienide;COT = C_8H_8~(2-),cyclooctatetraenide;Ln =Dy~(3+),Ho~(3+),Er~(3+)),which behave as a single-ion magnets(SIMs)[1-4].It opened a door of SMMs to the chemists in organometallic chemistry.Recently,we found that some new sandwich and half-sandwich lanthanide organometallic molecules could also show the slow relaxation of magnetization[5-8].Moreover,a few new linear two-coordinated Co(Ⅰ)/Co(Ⅱ) organometallic SIM were discovered[9-10].We hope these systems can provide new understandings of slow magnetic relaxation and new clues on the design and synthesis of molecular nanomagnets.; After the milestone discovery of the first single-molecule magnets(SMMs) Mn_(12)ac,many new SMMs were structurally and magnetically characterized.The most studied systems are mainly conventional coordination compounds with polynuclear structures.From 2011,we explored a series mononuclear organometallic sandwich molecules,Cp*LnCOT(Cp* = C_5Me_5~-,pentamethylcyclopenta-dienide;COT = C_8H_8~(2-),cyclooctatetraenide;Ln =Dy~(3+),Ho~(3+),Er~(3+)),which behave as a single-ion magnets(SIMs)[1-4].It opened a door o; 中国化学会; 1 |
