The soluble tetra-alkyl phthalocyanine compounds have the following general structure, wherein Rn represents straight-chain or branching chain alkane, n represents the number of straight-chain or branching chain alkane, M represents center ligand of bivalence or more, L represents axial ligand, X represents the number of L.

该可溶性四烷基酞菁化合物符合如下结构通式：结构通式中，Rn代表直链或支化链的烷烃，n代表直链或支化链的烷烃的数目，M代表二价或二价以上的中心配体，L代表轴向配体，X代表L的数目。

The integrated analytical results show that the novel ligand coexists in ketoform and enolform structures under the measuring conditions, the ketoform structure may change into the enolform structure during the coordination and bonds with the central ion by two O atoms of the enolized hydroxyl group of pyrazolone ring and H2O and the N atom of the imine group and the N atom containing H of benzimidazole ring by losing the proton. And the coordination number of these complexes is four.

综合各种分析结果显示：配体在测试条件下以酮式和烯醇式结构共存，配位时酮式可能转化为烯醇式结构，按去质子的方式以吡唑啉酮环羟基和H2O上的两个O原子以及亚胺基上的N原子和苯并咪唑环上的含氢N原子与中心离子成键，配合物的配位数为4。

Then, the multidentate amine immobilized on silica gel was used as ligand for CuCl in ATRA of CCl_4 with MMA and methyl trichloroacetate with St repeatly. The conversion and purity of the product were determined through the gas chromatography and ~1H NMR respectively. Finally, the multidentate amine immobilized on silica gel was used as ligand for CuCl in ATRP of St initiated by TCPP and MMA initiated by MMTCB. The number average molecular weights of the polymers were determined through GPC.

此多齿胺改性硅胶配体被分别多次重复用于四氯化碳与甲基丙烯酸甲酯，三氯乙酸甲酯与苯乙烯的ATRA反应中，通过气相色谱测定了原料的转化率随时间的变化，且通过核磁~1H NMR测定了产物的纯度，我们还进一步将此种多齿胺改性硅胶配体用于TCPP引发St的ATRP和MMTCB引发MMA的ATRP反应中，通过GPC测定所得聚合物的分子量。
