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. Molecule under investigation form 1D nanofibers which is polycrystalline in nature. As polarized emmision show varying intensities with changes in the angle of emmision polarizer, suggesting different orientation of crystal phases. Using the spectopolarimeter, we want to investigate supramolecule induced chirality due to molecular organization within the nanofibers. The experiment was carried out by dispersion of molecule from good solvent (chloroform) to poor solvent (methanol).

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。所研究的分子构成多晶性质的一维纳米纤维。随着发射偏振器角度的变化，极化发射的强度不同，表明晶体相的取向不同。利用光谱偏振仪，我们想研究由于纳米纤维内部分子组织而引起的超分子诱导手性。实验是通过将分子从良好溶剂（氯仿）分散到不良溶剂（甲醇）进行的。
