自旋交叉配合物的研究是分子磁化学中的一个重要领域 ,已引起人们的普遍关注 .近期我们设计、制备了配体 2 methyl 1,4,8,9 tetraaza triphenylene (mtt) ,并以此配体合成了一个新的高温自旋交叉配合物 [Fe(mtt) 2 (NCS) 2 ]·2 5H2 O .通过元素分析、核磁共振、红外光谱、电喷雾质谱和紫外光谱等方法对该配体和配合物进行了表征 .变温磁化率研究发现该配合物的自旋转换温度为Tc↑ =3 47K ,Tc↓ =3 43K ,回滞宽度 4K ,是体系 [Fe(L) 2 (NCS) 2 ]中自旋转换温度最高的 .与同体系其它配合物比较 ,发现配体的修饰对自旋交叉临界温度以及回滞宽度都有显著影响
Spin-cross complex research has become an important field in molecular magnetism, and has attracted people’s attention recently. We designed and prepared ligand 2 methyl 1,4,8,9 tetraazatriphenylene (mtt) The ligand synthesized a new high-temperature spin-coupled complex [Fe (mtt) 2 (NCS) 2] · 2 5H 2 O. The results of elemental analysis, nuclear magnetic resonance, infrared spectroscopy, electrospray ionization and ultraviolet spectroscopy The results show that the spin conversion temperature of this complex is Tc = 3 47K, Tc ↓ = 3 43K, kurtosis hysteresis 4K, and the system [Fe (L) 2 (NCS) 2] had the highest spin transition temperature.Compared with other complexes in the same system, it was found that the modification of the ligand had a significant effect on the critical temperature of spin crossing and the width of hysteresis

增密是实现春玉米超高产的基本条件,但增密又加剧了玉米个体的衰老进程,而果穗大小不同的品种对增密的反应不同。试验选用高秆大穗型和中秆中穗型两种穗型品种,在不同种植密度(7.5-12.0万株/hm~2)条件下,从根冠两个方面探索超高产春玉米的衰老特性。试验结果如下:1.不同种植密度处理下,超高产春玉米花粒期不同层位叶片间表现为下位叶衰老早于上位叶和穗位叶,穗位叶衰老速度最慢;不同土层根系衰老均呈现空间
