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. We keep developing new porphyrinic building blocks that feature pendant meso aryl groups bearing either 3',5'-(2",2"-dimethylbutyloxy) or 3',5'-[(triethylene glycol monomethyl ether)oxy] moieties. These precursors have made the syntheses of high molecular weight, ethyne- and butadiyne-bridged supramolecular multiporphyrin systems practical by dramatically enhancing their solubility. Many such structures have been fabricated to date in our laboratory, and basic photophysical properties are to be explored using TCSPC and nanosecond transient absorption measuements.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 我们不断开发新的卟啉结构单元，其特征是带有 3',5'-(2",2"-二甲基丁氧基) 或 3',5'-[(三乙二醇单甲醚)氧基] 部分的侧链内消旋芳基。 这些前体通过显着提高溶解度，使得高分子量、乙炔和丁二炔桥接的超分子多卟啉系统的合成变得实用。 迄今为止，我们的实验室已经制造了许多这样的结构，并且将使用 TCSPC 和纳秒瞬态吸收测量来探索基本的光物理特性。
