  A facile introduction of alpha,beta- or alpha,beta,gamma,delta-unsaturated ester functions onto porphyrins was achieved through rhodium-catalyzed addition of beta-borylporphyrins to acrylate or 2,4-pentadienoate esters. The reaction of meso-borylporphyrins with acrylates exclusively afforded saturated esters by 1,4-conjugate addition under the same reaction conditions. Thus, the reaction mode (Heck-type

  通过铑催化将β-硼基卟啉加到丙烯酸酯或2，4-戊二烯酸酯上，可以容易地将α，β-或α，β，γ，δ，δ-不饱和酯官能团引入到卟啉中。在相同的反应条件下，通过1，4-共轭加成，中硼烷基卟啉与丙烯酸酯的反应仅提供饱和酯。因此，反应模式（Heck型相对于共轭物的添加）高度依赖于反应位点（β对内消旋）。这种官能化对卟啉pi系统的电子性质有重大影响，它通过有效地通过β位置共轭，在吸收光谱中引起明显的红移和变宽。

  Two diazaporphyrin (DAP)-porphyrin hetero dimers, in beta-meso and beta-beta configurations, were prepared to study their photoinduced intramolecular electron transfer properties. The two meso nitrogen atoms in the porphyrin ring of DAP change its redox potential, making DAP more easily reduced, compared to its porphyrin counterpart. A charge-transfer from porphyrin to DAP in both hetero dimers was verified by versatile optical spectroscopic methods. The steady-state fluorescence spectra indicated an efficient intramolecular exciplex formation for both dimers. For the beta-meso dimer, ultrafast time-resolved spectroscopic methods revealed the subpicosecond formation of two types of primary short-living (1-18 ps) intramolecular exciplexes, which relaxed in toluene to form a long-living final exciplex (1.4 ns) followed by a longer-living charge transfer complex (>5 ns). However, in benzonitrile, the lifetime of the final exciplex was longer (660 ps) as was that of the charge transfer complex (180 ps). The beta-beta analogue formed similar short-living exciplexes in both solvents, but the final exciplex and the charge transfer state had significantly shorter lifetimes. The electrochemical redox potential measurements and density functional theory calculations supported the proposed mechanism.
