  Porphyrin Arrays Responsive to Additives. Fluorescence Tuning

  摘要：

  The application of low-flux sunlight begins with the synthesis of effective antenna systems. This requires the development of dye integrates with optimized dye orientation for effective energy transfer. We here report a series of peptide-linked porphyrin arrays, denoted by Boc-(Por(Zn,S))-OBut (n = 2, 4, and 8), that change their dye orientation to increase fluorescence responsively to additive reagents. The B-band absorption (AB) regions of the arrays show blue shifts (dimer, 407.6 nm; tetramer, 408.2 nm; octamer, 407.8 nm) in organic solvents as compared to that of Boc-Por(Zn,S)-OBut (monomer, 422.6 nm) and the fluorescence yield Phi' of the arrays decreases with increasing n, obeying the relationship Phi' = 0.03/n(1.5); however, the arrays are tuned up in fluorescence emission by the addition of 1,2-diaminoethane (en). The addition of a sufficient amount of en increases the fluorescence of the porphyrins in monomer, dimer, tetramer, and octamer by similar to 5, similar to 12, similar to 12, and >730 times, respectively, when compared with that observed in the absence of en. This also causes asymptotic red shifts in absorption (AB) bands (B-band lambda(max): 410 to 429-430 nm), as well as changes in circular dichroism (CD) spectra, and makes porphyrins approach new mutual asymmetric orientations. Our results show the potentiality of the tunable dye polymers that are a posteriori optimized in dye orientation and fluorescence emission by additive reagents for the development of effective light-harvesting materials.

  ruffle of the porphyrin increases with the number of meso substituents. (Octaethylporphyrin)nickel(II) undergoes nucleophilic substitution reactions upon treatment with alkylating reagents such as butyllithium, hydrolysis with water, and oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone [DDQ; Eq. (a)]. Alkylation can be achieved at all four meso positions, and access is provided to new nonplanar

  organolithium reagents, preferentially in the meso positions. The overall reaction is a nucleophilic substitution and proceeds via initial reaction of the organic nucleophile with a meso carbon yielding an anionic species which is hydrolyzed to a porphodimethene (5,15-dihydroporphyrin), formally constituting an addition reaction to two Cm positions. Subsequent oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone

  卟啉容易与有机锂试剂反应，优先在介孔位置。整个反应是亲核取代，并且通过有机亲核体与内消旋碳的初始反应进行，产生阴离子物质，该阴离子物质被水解为二甲叉二甲基（5,15-二氢卟啉），形式上构成了两个Cm位置的加成反应。随后用2,3-二氯-5,6-二氰基-1,4-苯醌（DDQ）氧化，生成内消旋取代的卟啉。该反应是高度通用的，因为它是用各种烷基或芳基锂试剂以很高的定量收率完成的。此外，LiR可用于与各种金属络合物（最好与NiII，但也可以与ZnII，CuII和CoII进行反应），最适用于游离碱卟啉。同样有利的是，该反应可以依次用于引入1、2、3或4个（不同的）内消旋取代基，从而首次使任何所需的内消旋卟啉进入。如果使用内消旋取代的卟啉，则可以使用与LiR的反应来制备phlorins（已知的反应），卟啉二烯（5,15-二氢卟啉，包括具有环外双键的卟啉，例如5（1），5 （2）-二氢卟啉）或二氢卟酚（2
