Complexation of copper(II) 2,3,9,10,16,17,23,24-octahydroxy-29H,31H-phthalocyanine (CuPcOH) with copper(II) ions gives a two-dimensional (2D) metal-organic framework (MOF). This is the first report of a phthalocyanine-based MOF. This 2D MOF was obtained as a black powder and showed an electrical conductivity of 1.6×10 S cm at 80 °C. When this MOF is used as a cathode of lithium ion battery (LIB), large charge/discharge capacities of 151/128 mAh g were obtained. In addition, it showed a good stability during 200 charge/discharge cycles. The obtained LIB performance mainly originates from the electrically conductive and redox-active framework of the phthalocyanine-based 2D MOF and its hierarchical microporous/mesoporous structure.

MIL-101(Fe) was investigated as a cathode material of lithium ion batteries. A battery test reveals that MIL-101(Fe) shows a charge and discharge capacitance of 110 mA h g. It also showed reversible charge and discharge cycles and uptake of 0.62 Li/Fe after 100 cycles, which is the highest loading amount ever reported for the carboxylic MOFs. It also operates in the temperature range up to 350 °C and showed a good high thermal stability.

We examined the effects of ornithine on the sleep-wake cycle by monitoring the electroencephalogram, electromyogram, and locomotor activity of freely moving mice after oral administration of it at lights-off time (18:00). Ornithine (1.0 and 3.0 g/kg of body weight) increased the amount of non-rapid eye movement (non-REM, NREM) sleep for 2 h after its administration, with a peak at 60 min post administration, to 164% and 198%, respectively, of that of the vehicle-administered mice, without changing the amount of REM sleep. The administration of ornithine at a lower dose (0.3 g/kg of body weight) did not increase the amount of NREM sleep compared with the vehicle administration. Ornithine did not affect the power spectrum density of NREM sleep but increased the number of episodes of wakefulness and NREM sleep and that of transitions between wakefulness and NREM sleep, and decreased the mean duration of wake episodes in a dose-dependent manner for 2 h after the oral administration. These results indicate that ornithine increased the amount of NREM sleep without reducing the power spectrum density of NREM sleep.
