This grant is being awarded under the Materials Chemistry Initiative. Work is proposed in which organic materials classes known to have a large non-linear optical response are incorporated into multilayer Langmuir-Blodgett (LB) films. For second harmonic generation, which requires a non-centrosymmetric structure, LB superlattices are proposed as a scheme to break the inversion symmetry usually found in LB films. The work is inherently interdisciplinary and combines a chemist and three physicist. It incorporates unique LB growth instrumentation (developed at Northwestern), strength in non-linear optical measurements, and the chemical and materials expertise of a major midwest industrials research laboratory (Amoco).

这项资助是在材料化学倡议下授予的。提出了将已知具有大非线性光学响应的有机材料类纳入多层Langmuir-Blodgett （LB）薄膜的工作。对于二次谐波的产生，需要一个非中心对称的结构，LB超晶格被提出作为一种方案来打破通常在LB膜中发现的反转对称性。这项工作本质上是跨学科的，结合了一位化学家和三位物理学家。它结合了独特的LB生长仪器（西北大学开发），非线性光学测量的优势，以及中西部主要工业研究实验室（Amoco）的化学和材料专业知识。
