PHOTOPHYSICAL STUDIES OF CONJUGATED MULTIPORPHYRIN COMPOUNDS

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。 合成了新的卟啉结构单元，其特征在于带有3 '，5'-（2”，2”-二甲基丁氧基）或3 '，5'-[（三乙二醇单甲醚）氧基]部分的侧链中位芳基。这些组件是潜在的令人兴奋的类似物的光合阵列和蛋白质相关的生物材料。前体的合成，高分子量，乙炔和丁二炔桥接的超分子多卟啉系统的实用显着提高他们的溶解度。现在已经合成了许多这样的结构，并且将使用时间分辨荧光和吸收光谱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. New porphyrinic building blocks that feature pendant meso aryl groups bearing either 3',5'-(2",2"-dimethylbutyloxy) or 3',5'-[(triethylene glycol monomehtyl ether)oxy] moieties are synthesized. These assemblies are potentially exciting analogues of photosynthetic arrays and protein associable biomaterials. Precursors have made the synthesis of high molecular weight, ethyne- and butadiyne-bridged supramolecular multiporphyrin systems practical by dramatically enhancing their solubility. Many such structures have now been synthesized, and basic photophysical properties are to be explored using time resolve fluorescence and absorption spectroscopy.
