Many of the comforts of modern society such as LED lighting, TV displays, computers and clean energy generation are built using fundamental discoveries in inorganic chemistry. If one can control how atoms are assembled into higher ordered structures then the logical fabrication of advanced materials with improved light emitting, insulating/conducting or stimuli responsive behavior can be developed. In this proposal we adopt a two-pronged approach to access functional solid state materials (such as efficient electrical insulators for nanoscale circuitry) and flexible plastic-based electronics by focusing on economical, safe and mild fabrication procedures. In approach #1, we will use molecular tweezers, termed donors, to hold onto reactive molecular species that were either unknown, or only isolable in free form in the gas phase or under cryogenic conditions. Once trapped, we will then coax the donors to release their reactive molecular cargo by either mild heating or chemical treatment to enable the spontaneous growth of materials with pre-programmed structure and function. Focus will be given to methods that operate in commonly available organic solvents in order to later fabricate optoelectronic devices in a cost-effective manner. In approach #2, we combine efficient atom exchange chemistry with Nobel Prize (2010) winning chemical bond-forming chemistry to generate polymeric (plastic) materials for flexible light emitting devices (LEDs). This combined approach gives us the power to dial in the appropriate atom combinations and structural arrangements (e.g. ring shaped units) which should give us rapid access to high performance materials. Both of these approaches have the potential to be universally adopted by the scientific and industrial communities and should help to advance Canada's position as a leading innovator in clean energy (i.e. low energy lighting via non-toxic LEDs) and computing/information storage by providing new routes to next generation device components.

现代社会的许多舒适感，例如LED照明，电视显示，计算机和清洁能源产生都是使用无机化学中的基本发现建造的。如果可以控制原子如何组装成较高有序的结构，则可以开发出具有改进的光发射，绝缘/导电或刺激反应性行为的高级材料的逻辑制造。在此提案中，我们采用了两种供电的方法来访问功能性固态材料（例如用于纳米级电路的有效电绝缘体）和灵活的基于塑料的电子设备，通过着重于经济，安全和轻度的制造程序。在方法＃1中，我们将使用称为供体的分子镊子保留不明的反应性分子物种，或者仅在气相或低温条件下以自由形式隔离。一旦被困，我们将通过轻度加热或化学处理来哄骗供体释放其反应性分子货物，以使具有预编程的结构和功能的材料自发生长。将重点放在通常可用的有机溶剂中运行的方法，以便以后以具有成本效益的方式制造光电设备。在方法2中，我们将有效的原子交换化学与诺贝尔奖（2010）赢得化学键合化的化学结合，以生成用于柔性发光装置（LED）的聚合物（塑料）材料。这种组合方法使我们有能力拨入适当的原子组合和结构布置（例如环形单元），这应该使我们可以快速访问高性能材料。这两种方法都有可能被科学和工业社区普遍采用，并应有助于提高加拿大作为清洁能源领域的领先创新者的地位（即通过无毒的LED进行低能照明）和计算/信息存储，并通过为下一代设备组件提供新的路线。
