This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The main objective of the proposal was to characterize the crystalline packing for a variety of self-assembled nanostructures of the organic semiconducting molecules fabricated by pi-pi stacking. In general q-value for the pi-pi stacking is close to 1.8 which is 0.34 nm in d-spacing units (as found in graphite). Thus, by measuring the WAXS in the q-range of 0.01 to 3.0 ¿-1 the packing behavior for each of the self-assembled nanostructure could be deduced. Such a measurement provides a pathway to understand the detailed structure-property-function relationships through which one can expect to tailor better organic molecules for optimized performance.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 该提案的主要目的是表征通过π-π堆叠制造的有机半导体分子的各种自组装纳米结构的结晶堆积。通常，π-π堆叠的q值接近1.8，其在d间距单位中为0.34 nm（如在石墨中发现的）。因此，通过在0.01至3.0 <$-1的q范围内测量WAXS，可以推导出每个自组装纳米结构的堆积行为。这种测量提供了一种途径来理解详细的结构-性质-功能关系，通过这种关系，人们可以期望定制更好的有机分子以优化性能。
