Methods for producing a stabilised alpha copper phthalocyanine are described. More specifically such methods comprise forming a mixture of (a) a compound of the general formula (II), in which, R1 and R2 are independently -CN or -C(O)OH, or R1 and R2 together are -C(O)OC(O)-, -C(O)NHC(O)- or -C(NH)NH(NH)C-, and form a fused five-membered ring structure and R3, R4, R5 or R6 which may be the same or different are -H, a halide, an C1- C5 alkyl, or a substituent group containing a heteroatom; and (b) a tethered compound of the general formula (III), wherein, any adjacent two of R7, R8 and R9 and any adjacent two of R12, R13 and R14 are independently -CN or -C(O)OH, and any of R7, R8, R9, R12, R13 and R14 which are not -CN or - C(O)OH, are -H, a halide, a C1 - C5 alkyl or a substituent group containing a heteroatom, or any adjacent two of R7, R8 and R9 and any adjacent two of R12, R13 and R14 are either -C(O)OC(O)-, -C(O)NHC(O)- or -C(NH)NH(NH)C-, and form a fused five-membered ring structure, the ring structures being the same or different and any R substituents that are not part of the ring structure are -H, a halide, a C1 - C5 alkyl or a substituent group containing a heteroatom; and X is a chain having a backbone of up to two substituted or unsubstituted atoms and the chain comprises an alkane, an alkene or an alkenyl group or a group containing at least one heteroatom; and reacting the mixture with a source of copper in the +I or +II oxidation state to form copper phthalocyanine in predominantly the alpha crystalline form.
描述了生产稳定的α铜酞菁的方法。更具体地,这些方法包括形成一个混合物,其中(a)是通式(II)的化合物,其中,R1和R2独立地为-CN或-C(O)OH,或者R1和R2一起为-C(O)OC(O)-,-C(O)NHC(O)-或-C(NH)NH(NH)C-,并形成融合的五元环结构,R3、R4、R5或R6可以相同也可以不同,分别为-H、卤素、C1-C5烷基或含有杂原子的取代基;以及(b)是通式(III)的锚定化合物,其中,R7、R8和R9中的任意相邻两个和R12、R13和R14中的任意相邻两个独立地为-CN或-C(O)OH,而不是-CN或C(O)OH的R7、R8、R9、R12、R13和R14中的任何一个为-H、卤素、C1-C5烷基或含有杂原子的取代基,或者R7、R8和R9中的任意相邻两个和R12、R13和R14中的任意相邻两个为-C(O)OC(O)-、-C(O)NHC(O)-或-C(NH)NH(NH)C-,并形成融合的五元环结构,环结构可以相同也可以不同,不属于环结构的任何R取代基为-H、卤素、C1-C5烷基或含有杂原子的取代基;X是具有最多两个取代或未取代原子的骨架链,该链包括烷烃、烯烃或烯基基团或含有至少一个杂原子的基团;并将该混合物与处于+I或+II氧化态的铜源反应,形成主要为α晶形的铜酞菁。
