The use of chlorins as photosensitizers or fluorophores in a range of biological applications requires facile provisions for imparting high water solubility. Two free base chlorins have been prepared wherein each chlorin bears a geminal dimethyl group in the reduced ring and a water-solubilizing unit at the chlorin 10-position. In one design (FbC1-PO3H2), the water-solubilizing unit is a 1,5-diphosphonopent-3-yl
在许多生物学应用中,使用二氢卟酚作为光敏剂或荧光团需要提供高水溶性的简便设备。已经制备了两种游离碱二氢卟酚,其中每个二氢卟酚在还原环上具有双甲基二甲基基团,并且在二氢卟酚10-位具有水增溶单元。在一种设计中(FbC1-PO 3 H 2),水溶性单元是1,5-二膦基叔丁基-3-基(“燕尾”)单元,以前曾被用于卟啉以达到良好的效果。在另一种设计中(FbC2-PO 3 H 2),水溶性单元是2,6-双(膦酰基甲氧基)苯基单元。开发了两条互补的路线来制备FbC2-PO 3 H从图2中可以看出,需要将保护的膦酸酯部分引入二氢卟酚的东半部前体中,或通过完整二氢卟酚的衍生化而引入。除去膦酸酯保护基团后,在每个合成的最后一步中都实现了水溶性。二氢卟酚FbC1-PO 3 H 2和FbC2-PO 3 H 2具有很高的水溶性(> 10 mM),如1 H NMR光谱法(D 2)所示O)和紫外可见吸收光谱。使用静态

were prepared in good yields (35-50%) and display unusual multielectron redox and photochemical properties. Each phlorin can be oxidized up to three times at modest potentials and can be reduced twice. The electron-donating and electron-releasing properties of the ancillary aryl substituent attenuate the potentials of these redox events; phlorins containing electron-donating aryl groups are easier to

charge transfer intersystemcrossing (SOCT-ISC) process have recently attracted attention due to their potential to replace costly transition metal complexes in photonic applications. The efficiency of SOCT-ISC in BODIPY donor-acceptor dyads, so far the most thoroughly investigated class of such sensitizers, can be finely tuned by structural modification. However, predicting the triplet state yields and

A highly efficient porphyrin synthesis facilitates a systematic investigation of the effects that secondary substituents have on the physical properties, crystal structures, and nanoparticle morphologies of amphiphilic (porphyrin)Sn(OH)2.
This study describes synthesis of ABCD-porphryin Pt(II) complexes via dehydrative aromatization in one-pot from corresponding dipyrrinatoPt(II) complexes and bisformyldipyrrins. This procedure also enables the construction of a C1-symmetrical ABCD-porphyrin with intrinsic chirality from achiral precursors. The photophysical properties of obtained molecules are also described in detail.
