Phthalocyanines of formula (I) are described wherein M is a metal atom, metal compound or is 2H; one H being bonded to each of the two nitrogen atoms depicted as being bonded to M (positions 29 and 31 shown); R.sub.1 -R.sub.25 may be the same or different and are chosen independently from the following groups: straight or branched chain alkyl containing up to 32 carbon atoms where 1 or more non-adjacent CH.sub.2 groups may be replaced by O and/or a double bond; H; F; and at least one of R.sub.2.3.9.10.16.17.34.24 is chosen from formula (II) wherein Y, X and Z are chosen independently from HO, `O, --O, OR, H, C.sub.1-16 branched or straight chain alkyl or alkoxy; X and Z may also be selected from phenyl groups which may be, independently of each other, substituted with one or more C.sub.1-5 straight or branched chain alkyl groups; R may be C.sub.1-16 branched or straight chain alkyl or alkene wherein 1 or more non-adjacent CH.sub.2 groups may be replaced by O and may be terminated by an OH group; provided that at least one of Y, X and Z is chosen from HO, `O, --O, OR. Compounds of the above formulae are useful in a broad range of applications, including electro-optical devices, Langmuir Blodgett films, molecular wires, in optical recording media and uses which exploit their redox properties.
描述了式(I)的酞菁,其中M是金属原子、金属化合物或2H;其中一个H与所示与M相结合的两个氮原子(位置29和31)中的每一个相结合;R.sub.1-R.sub.25可以相同也可以不同,并且可以独立地从以下组中选择:直链或支链烷基,含有多达32个碳原子,其中1个或多个非相邻的CH.sub.2基团可以被O和/或双键所代替;H;F;并且R.sub.2.3.9.10.16.17.34.24中的至少一个选择自式(II),其中Y、X和Z可以独立地选择自HO、`O、-O、OR、H、C.sub.1-16支链或直链烷基或烷氧基;X和Z还可以选择自苯基,它们可以独立地被一个或多个C.sub.1-5直链或支链烷基取代;R可以是C.sub.1-16支链或直链烷基或烯烃,其中1个或多个非相邻的CH.sub.2基团可以被O代替,并且可以以OH基团终止;但要求Y、X和Z中的至少一个选择自HO、`O、-O、OR。上述式的化合物在广泛的应用中有用,包括电光器件、Langmuir Blodgett膜、分子导线、光记录介质和利用它们的氧化还原性质的用途。
