研究了[（μ2-6-甲基-2-吡啶甲乙醇）2{Cu（6-甲基-2-吡啶乙醇）}2](PF6)2的热致变色行为。根据单晶x射线晶体学研究，配合物在296 K和100 K之间没有显着变化。根据磁化率计算，在300 K和100 K时，三重态的占据率分别为55%和16.9%。该配合物在不同温度下的照片和量子计算表明，热致变色行为是由三重态和单重态之间的自旋态改变引起的。
This study explored the thermochromic behavior of [(μ2-6-methyl-2-pyridinemethanolate)2{Cu(6-methyl-2-pyridinemethanol)}2](PF6)2. The complexes show no significant variation between 296 K and 100 K according to a single-crystal X-ray crystallographic investigation. The occupancy of the triplet at 300 K and 100 K is 55% and 16.9%, respectively based on magnetic susceptibility. Photographs of the complex at different temperatures and quantum calculation exhibit that the thermochromic behavior is induced by the alteration of spin state between triplet and singlet.
