The push-pull electronic and steric effect of copper porphyrin catalysts on the cross-dehydrogenative coupling (CDC) reaction between the hydroxyl group of phenol substrates and C(sp3)-H bond have been investigated. Results showed that copper porphyrin bearing electron-withdrawing, bulky steric hindrance or heteroatom of pyridyl groups could increase the catalytic activity in the reaction. 5,10,15,20-(tetrakis(4-pyridyl)porphyrin)copper (CuTPyP) was found the best among all tested catalysts. Phenol substrates bearing various functional groups afforded moderate to excellent yields (99%). Significantly, as compared to other tested copper porphyrins, CuTPyP not only exhibited remarkable higher activity but also could shorten the reaction time from 12 to 6 h.

In this work, a series of asymmetric and symmetric porphyrin derivatives (structure types: A4, A3B1,trans-A2B2,cis-A2B2, A1B3, and B4) have been synthesizedviaa one-pot method and characterized by TLC, HPLC, FT-IR,1H-NMR and UV-Vis to identify their structures and properties. The porphyrin derivatives withtrans-A2B2andcis-A2B2structures are visually distinguishedviasingle-crystal X-ray diffraction; the crystal morphology oftrans-A2B2is a needle-like structure. All porphyrin derivatives (I-VI) have excellent nonlinear optical (NLO) and optical limiting (OL) properties, and are investigated using the standardZ-scan technique. Porphyrin derivativeIIIexhibits the maximum nonlinear absorption, nonlinear refraction coefficients and optical limitation threshold, and the values are 3.7 × 10?9m W?1, ?17 × 10?17m2W?1and 0.11 J cm?2, respectively. The results demonstrate that the introduction of different substituent numbers (mono-, di- and tri-, tetra-) and substituent sites (trans-A2B2andcis-A2B2) in the porphyrins could influence the NLO and OL properties. Structure regulation of porphyrin can lead to the adjustment of NLO and OL properties, and affect its practical NLO application in the future.
Combining metalloporphyrins and cyclometalated complexes – A luminous pair?

Cyclometalation is investigated as a method to modulate the photophysical properties of phosphorescent (benzo)porphyrins. For cyclometalation with Pt(II), 2-pyridyl groups were incorporated into three Pd(II) porphyrin complexes. Integration of the freely rotating cyclometalated 2-phenylpyridyl based motif in meso-position does not lead to notable spectral changes and only affects the luminescence decay time (about 2-fold decrease) in solution at room temperature. The decay times, however, are not affected in frozen glass at 77 K or immobilized into a rigid polystyrene matrix. In contrast, cyclometalation involving a 2-pyridyl unit in meso-position and the β-H of the porphyrin results in a large bathochromic shift (~ 1900 cm?1) of Q-bands in the absorption spectrum and the phosphorescence peak. A drastic decrease of the phosphorescence lifetime (about 20-fold) also is observed. Cyclometalation is accompanied by an increase of the singlet oxygen quantum yield to 85 % making the new dye a powerful red-light excitable 1O2 photosensitizer.
