PHOTOPHYSICAL STUDIES OF CONJUGATED MULTIPORPHYRIN COMPOUNDS

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。我们不断开发新的卟啉类构建块，其特征是带有3',5'-（2 ',2 '-二甲基丁氧基）或3',5'-[（三甘醇单甲基醚）氧]基团的悬垂中位芳基。这些前体通过显著提高其溶解度，使得高分子量、乙炔和丁二炔桥接的超分子多卟啉体系的合成成为可能。到目前为止，我们的实验室已经制造了许多这样的结构，并将使用TCSPC和纳秒瞬态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.
