光固化牙科材料的聚合开始使用camphorquinone (CQ)(λmax = 468海里)三级芳基胺(Norrish-II类型)的波长400 - 500纳米。另外,acylphosphine氧化物(APO;λmax = 385 nm)和bisacylphosphine氧化物(BAPOλmax = 397海里)由芳基胺用于避免变色。的低溶解度BAPO有限VIS-absorption APO限制他们的许多应用潜力。[1,2]的强烈吸收和散射波长390 - 420纳米之间methacrylate-based修复材料限制的深度photocure (DOC)实现在可接受的时间。达到4毫米的医生要求从所谓„Bulk-Filling“恢复复合材料,基于bisacyl-germane(包心菜)发起人Ivocerin®(λmax = 408海里)。(3、4、5)为进一步改善医生,bathochromically转移发起者。小说通用电气,Sn-based发起者,比如tetraacyl-germane(为主)和锡烷(TASn)发起人在此讨论相比Ivocerin®。(6、7、8)而λmax为主和TASn没有红移相对于Ivocerin,在440 - 480海里重叠的吸收更好与牙科光固化机的发射光谱(LCU)。段和TASn快速光解的结果完全在10 s辐照使用LCU和不可逆转的漂白(390 - 510海里)。牙科复合材料组成的克分子数相等的浓度的发起者(0.2 wt. %包心菜,0.4 wt. %为主和TASn)比较对医生在不同波长(400 - 517 nm)。 Here, TASn gave an increased DOC at higher wavelength in comparison to BAGe. The presented systems are highly interesting alternatives to commercially available photo initiators. Their highly effective radical generation, excellent photobleaching, excitation at biocompatible wavelengths and low toxicity of photolysis products offer great potential for a variety of different medical and industrial applications.
