3,6‐Dibromophthalonitrile was successfully synthesized from 3,6‐dihydroxyphthalonitrile using triphenylphosphine dibromide as bromation reagent. Starting from 3,6‐dibromophthalonitrile, synthesis of 1,4,8,11,15,18,22,25‐octakis(4‐dodecylthiophen‐2‐yl)phthalocyaninatozinc(II) (ZnPc) was described. TGA demonstrated the perfect stability of ZnPc. The newly prepared ZnPc that was symmetrically substituted with thienyl substituents results in an intensively red‐shifted Q‐band. The HOMO and LUMO values of ZnPc were acquired by CV.

在外围α-位置具有8个噻吩基取代基的3,6-二溴邻苯二甲腈和酞菁的新合成

以三苯基膦二溴化物为溴化试剂，成功地由3,6-二羟基邻苯二甲腈合成了3,6-二溴邻苯二甲腈。从3,6-二溴邻苯二甲腈开始，描述了1,4,8,11,15,18,22,25-辛基（4-十二烷基噻吩-2-基）酞菁锌（II）（ZnPc）的合成。TGA证明了ZnPc的完美稳定性。新制备的被噻吩基取代基对称取代的ZnPc导致强烈的红移Q波段。通过CV获得ZnPc的HOMO和LUMO值。
