SBIR Phase I: Design and Synthesis of Novel n-Type Organic-Inorganic Hybrid Dendrimers

这个小企业创新研究第一阶段项目旨在证明利用聚合合成方法合成新型杂交树状大分子的可行性。由于混合结构的纳米晶体核心和外围基团的光学和电子特性的协同作用，这些树状大分子将表现出增强的太阳能光收集、发光、电子传输、光子和其他电子和光电子特性。此外，这些树状大分子在300℃时具有热稳定性，可溶于常见的有机溶剂，如四氢呋喃、氯仿、二氯甲烷、甲苯、氯苯和环己烷。混合电子材料通过实现光伏电池、有机发光二极管、激光器、开关、存储器件和传感器，将对经济和环境产生重大影响。新型混合树突状分子可以制造出节能装置。据估计，到2025年，固态照明可以将全球照明用电量减少50%。仅在美国，累积的影响将是：(a)节省16.6 Quad （760 GW/Quad）的电能，(b)减少2.58亿吨碳排放，(c)不需要建造133座发电站（每座1000兆瓦），(d)累计节省1150亿美元（1998年美元）的资金。

This Small Business Innovation Research Phase I project aimes to demonstrate the feasibility of synthesizing novel hybrid dendrimers utilizing a convergent synthetic approach. These dendrimers will exhibit enhanced solar light harvesting, light emitting, electron transporting, photonic, and other electronic and optoelectronic properties because of synergy in the optical and electronic properties of the nanocrystal core and peripheral group of the hybrid architecture. In addition, these dendrimers will be thermally stable 300 C and soluble in common organic solvents such as tetrahydrofuran, chloroform, dichloromethane, toluene, chlorobenzene and cyclohexane. Hybrid electronic materials will have major economic and environmental impact through realizing photovoltaic cells, organic light emitting-diodes, lasers, switches, memory devices, and sensors. Novel hybrid dendrimers can lead to energy efficient devices. It has been estimated that by 2025, Solid State Lighting could reduce the global usage of electricity for lighting by 50%. The cumulative impact in the U.S. alone would be: (a) saving 16.6 Quads (760 GW/Quad) of electrical energy, (b) eliminating 258 million metric tons of carbon emission, (c) removing the need for building 133 power stations (1000 MW each), and (d) cumulative financial savings of $115 Billion (1998 dollars).
