4-acyloxy- and 4-acylaminophthalonitriles and phthalocyanines based thereon
摘要:
Reactions of 4-hydroxy- and 4-aminophthalonitriles with substituted benzoyl chlorides gave the corresponding N- and O-benzoyl derivatives, and the latter were used to obtain copper and nickel phthalocyanine complexes. Effect of the substituents in the latter on their electronic absorption spectra was studied. The obtained complexes were found to undergo association in organic solvents.

at alternate interplane distances (3.182 and 3.318 Å). Magnetic susceptibility measurements for polymorph α indicate strong antiferromagnetic interactions along the 1D regular chain. Magnetic susceptibility data cannot be fully fitted to the Bonner and Fischer model for the 2–300 K temperature range. The steeper rise in paramagnetism above 80 K was rationalized by temperature-dependent antiferromagnetic
1,3-二苯基-1,4-二氢苯并[ e ][1,2,4]三嗪-4-基-6,7-二甲腈是一种极其稳定的缺电子有机自由基,具有用作建筑的潜力阻止一系列电子和自旋电子材料。该自由基具有完全可逆的单电子氧化还原并且高度离域,一些自旋密度可达到腈基团。通过单晶 X 射线衍射法鉴定并表征了两种多晶型物α和β 。两种多晶型物均形成一维 (1D) π 堆叠。然而,在多晶型物中,α自由基位于均匀的面间距离(3.366 Å),而在多晶型物中,β自由基位于交替的面间距离(3.182和3.318 Å)。多晶型物α的磁化率测量表明沿一维规则链存在强烈的反铁磁相互作用。磁化率数据无法完全拟合 2–300 K 温度范围的 Bonner 和 Fischer 模型。80 K 以上顺磁性的急剧上升是通过一维 π 堆栈内自由基之间依赖于温度的反铁磁交换相互作用合理化的,这确实得到了密度泛函理论 (DFT) 计算的支持。采用第一
