Preparation of Novel Degradation Recognition Fluorescent Additives for Industrial Use Lubricating Oil

合成了大量含有长链碱性烷基铵阳离子芳香族部分和/或长链烷基硫代膦阳离子芳香族部分的有机配体，使其对润滑油具有良好的溶解性能。其次，合成了与配体基团相对应的大规模稀土配合物。虽然用X-射线单晶结构分析仪进行了测量，但在发射强度下，为了明确配合物的构型绝对结构，通过取代基链长度的锥形绝对结构来改变结构，在发射强度下很难奏效。碳链长度较短(C&lt；6)，结构为锥形结构。另一方面，碳链长度反转较长(C&lt；6)，碳链长度较长(C&gt；6)，结构为1，2-交替结构。

It were synthesized large-amount organic ligands which contained long-chain basic alkyl ammonium cation aromatic moiety and/or long-chain alkyl-thio phosphonium cation aromatic moiety for the good solubility to lubricating oil. Next, It were synthesized the large-scale lanthanide complexes which corresponded from the ligand group. It was proven to be seldom effective at the emission intensity, in order to clear the configuration absolute structure of the complex, though the measurement is carried out using the X-ray single crystal structure analyzer, and the structure changes by the substituent chain length with cone type absolute structure. The lengths of the carbon chains are short(C<6), the structure of the complexes have the cone type structure. On the other hand, the lengths of the carbon chains are reversely long(C<6), the carbon chain lengths are long(C>6), the structures of the complexes have1,2-alternate structure.
