Aiming at two key issues in the molecular design of high-spin moleculesand organic ferromagnets, i.e., the ferromagnetic coupling strength in localradical fragments and the changeover of coupling capabilities offerromagnetic coupling units in building high-spin molecules, we made anextensive and deep investigation on numerous important conjugated radicalsystems within the semiempirical and nonempirical VB model, respectively.

针对高自旋分子和有机铁磁体的分子设计中的两个重要问题，即自由基片断的铁磁偶合强度及铁磁偶合单元在&建造&高自旋分子时其偶合能力的变化，分别用半经验的和非经验的VB模型，以一些重要的共轭自由基体系为对象进行了广泛而深入的研究。

When two particles couple themselves in a singlet at short distances (one with spin up and one with spin down) the new nonlinear, nonlocal and nonpotential forces due to deep wave-overlappings are so attractive to overcome possible repulsive Coulomb forces, and permit new bound states at short distances which simply cannot be conceived - let alone treated - by quantum mechanics and chemistry.

当两个粒子在很小的作用距离内相互偶合成为零自旋态〔一个上旋而另一个下旋〕，深深重叠在一起的波导致新型的非线性、非局部和非潜势力的引力大到得以克服相互排斥库伦力，允许很小相互作用距离内的一种新的限制状态。量子力学和量子化学无法考虑，更不用说去处理，这种新的限制状态。

In order to enhance the miscibility between the inorganic and the organic phases,the silanol coupling agent is made from the slane VTMS and the colloid silica. Then the silanol coupling agent and nano-particles of ZnSb2O6 as the conductive filler are successfully bonded and the nano-particles of ZnSb2O6 will become more organic-like. The colloid silane-SiO2-ZnSb2O6 precursor solution is subsequently mixed with a homogeneous lsopropylalcohol solution of SR-399 acrylic monomers (Dipentaerythritol pentaacrylate) and the active free radical agent709. Under nitrogen purging, this reaction solution prepolymerize at 60℃. Then, the solution is spin-coated with the spin coator at room temperature. At last, the coated thin film is cured and crosslinked by the UV curing reactor to form the highly transparent thin film with good optoelectronic properties from hybrid organic-inorganic nano-composite.

首先以矽氧烷VTMS和colloid silica制备矽氧偶合剂，再以此偶合剂对分散於异丙醇溶液之奈米级的colloid ZnSb2O6做有机化改质，以增进其与有机高分子基材的键结相容性，我们将此colloid silane-SiO2 - ZnSb2O6前驱物与SR-399有机基材单体(Dipentaerythritol pentaacrylate)的异丙醇溶液与活性自由基光起始剂709均匀掺混后，在充满氮气反应系统下，加热至60℃进行预聚合反应，接著在室温下以旋转涂布机旋转涂布成厚度均匀薄膜，最后将此薄膜直接高温硬化或以UV硬化机网状键结硬化成透明与具部份导电性等光电特性之无机/有机奈米混成薄膜。
