Geometrically homogenous series of covalently linked zinc/free-base porphyrin dimers of varying length; design, synthesis and characterization

Singlet excitation energy transfer, SEET, can be mediated by a bridge, connecting an energy donor and acceptor, via a superexchange mechanism. The mediation efficiency depends on the energy difference between the first excited states of the donor and the bridge, ΔEDB, as well as the donor-acceptor distance, RDA. We have previously constructed a series of donor-bridge-acceptor, D-B-A, systems that allowed us to study how SEET depends on ΔEDB. To expand this study into a second dimension, the distance dependence, a new series of D-B-A systems were constructed. This series was based on the same zinc/free-base porphyrin couple as the donor-acceptor pair in the previous series. Their relative orientation was also retained. In contrast to our first series, the bridges in the latter were of varying length. The bridges were oligo(phenyleneethynylene)phenylene (OPE) structures and the length was systematically changed by increasing the number of phenyleneethynylene units from 1 to 4. To obtain high quality samples, the D-B-A systems were assembled by a building block approach where the zinc and free-base porphyrins were introduced separately using Heck alkynylations. The performance of the OPE structure as a mediator and scaffold is discussed in terms of singlet excited state energies and flexibility. For the first time, when combining the topical D-B-A systems with our previous subset, a homogeneous series of D-B-A systems has been synthesized that allows for studies of both the distance dependence and the energy difference dependence of SEET.

Modular Synthesis of Benzene-Centered Porphyrin Trimers and a Dendritic Porphyrin Hexamer

Rigid, star-shaped D3-symmetric arrays have been synthesized in which three porphyrin macrocyeles are attached to the 1,3, and 5 positions each of a benzene core through linkers consisting of collinear repetitive phenylethynyl units. Using the

Sequential catalytic synthesis of rod-like conjugated poly-ynes

Several poly-ynes X-[C ≡ C-C6H4-](n)C ≡ C-Si(i)Pr3 (X = H, SiMe3) with controlled length (n = 1, 2, 3, 4) have been prepared from the easily accessible 4-trimethylsilylethynyl iodobenzene by using iterative and convergent methods based on both Pd/Cu catalysed C-C cross-coupling and selective desilylation reactions.
