Disclosed are azulenocyanine compounds, method of making the same, and their use as semiconductor and absorber for organic photovoltaics. The azulenocyanine compounds according to the present invention have the following formula (I) or its regioisomers :
wherein M is selected from the group consisting of 2H (metal free analogue), metal cations in the oxidation state +2, preferably Zn(II), Mg(II), Cd(II), Cu(II), Ni(II), cations in the oxidation state >+2, preferably Ti(IV)O, V(IV)O, Al(III)X, Si(IV)X2, Sn(IV)X2, and Ge(IV)X2, wherein X is selected from halides, OH and ORa with Ra being alkyl groups or aryl groups ; and at least one of R1, R2 and R3 is selected from the group consisting of -CH2-R", -N=N-R', -COH(R')2, -CH=CH-R"', and -C≡C-R"'.
本发明公开了偶氮菁化合物、其制造方法及其作为半导体和有机光伏吸收剂的用途。根据本发明的偶氮菁化合物具有下式 (I) 或其 Regioisomers :
其中 M 选自 2H(无金属类似物)、氧化态 +2 的金属阳离子,最好是 Zn(II)、Mg(II)、Cd(II)、Cu(II)、Ni(II)、氧化态 >+2 的阳离子,优选 Ti(IV)O、V(IV)O、Al(III)X、Si(IV)X2、Sn(IV)X2 和 Ge(IV)X2,其中 X 选自卤化物、OH 和 ORa,Ra 为烷基或芳基;R1、R2 和 R3 中至少有一个选自由-CH2-R"、-N=N-R'、-COH(R')2、-CH=CH-R"'和-C≡C-R"'组成的组。
