PHOTOPHYSICAL STUDIES OF CONJUGATED MULTIPORPHYRIN COMPOUNDS

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。我们不断开发新的卟啉构筑块，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]基团的侧链中芳基。这些前体极大地提高了它们的溶解性，使高分子、乙炔和丁二炔桥联的超分子多卟啉体系的合成变得实用。到目前为止，我们实验室已经制作了许多这样的结构，并将使用TCSPC和纳秒瞬时吸收测量来探索基本的光物理性质。

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.
