Outline of Final Research Achievements

We have developed a novel ferroelectric porous molecular crystal of [Cu3La2(iminodiacetate)3](C2H5OH)x, and found when the guest molecular is changed by Ethanol molecular, the system will turn to ferroelectric around room temperature (260K). The hysteresis loop was observed just below Tc. We also synthesized an antiferromagnetic porous molecular crystal of Co3[C6H4(COO)2]2(C6H4C2O4H)2. The crystal has large size with two dimensional porous structure. The guest molecule are easily removed by vacuum condition, and it is possible to substitute with organic π molecular. In order to investigate these conducting porous crystals, we have modified the high pressure electrical transport measurement technique by using a diamond anvil cell. We found that by using our technique could provide high quality hydrostatic pressure up to very high pressure.
