Synthesis, Characterization and Weak Intramolecular Interactions of Porphyrins Bearing Nucleobases

Abstract

whereas the spectra of their zinc complexes show 7 nm red shifts of the Soret bands compared to that of ZnTPP. The emission spectra of Zn-1 and Zn-2 are independent of excitation wavelength. From combination of the evidence of absorption * and emission spectra it is suggested the existence of intramolecular metal-n interaction in Zn-1 and Zn-2. The results of conformational analysis agreed quite nicely with that of experiments, thus it was further to validate the experimental conclusions.

Synthesis of Porphyrins Di‐ and Tetra‐Functionalized with Nucleobases

“…For instance, the uracil-functionalized porphyrins described by Drain et al, [14] the water-soluble NB-porphyrins reported by Maiya et al [15] and the NB-porphyrin hybrid compounds described by Schneider et al [16] were synthesized by an Adler synthesis, [17] alkylation reactions of NB's active amine sites and by a condensation reaction between corresponding NBs and porphyrin derivatives respectively. Furthermore, the synthesis of porphyrins bearing nucleobases via ethoxy and acetyl linkers [18] or via amide linkers [19] was also reported. Taking into consideration the previously followed synthetic pathways, we developed two new simple approaches to synthesize NB-porphyrins architectures.…”

An unsymmetrical porphyrin and its metal complexes: Synthesis, spectroscopy, thermal analysis and liquid crystal properties

“…[1][2][3][4][5] Porphyrin liquid crystals 6 are of interest for optoelectronic and other device applications due to their synthetic versatility, thermal stability, large electron systems and photochemical properties. These properties make them useful materials for charge transport, photoelectronic conversion, non-linear optics, organic light emitting diodes and optical information storage.…”
