Porphyrin Core

We have developed a new strategy involving ‘click’ chemistry to prepare porphyrin-core dendrimers with peripheral coumarin moieties. They exhibit nematic discotic phases with hole mobilities among the highest values described in liquid crystals. Moreover, excitation of the coumarin moieties leads to energy transfer (antenna effect) to the porphyrin core.

Porphyrin Core

Click chemistry has been successfully applied to prepare a conjugate of zinc(II) porphyrin with four boron dipyrromethene moieties. Upon excitation at the latter, an efficient excitation energy transfer to the porphyrin core occurs with an energy transfer quantum yield of 0.98, making this conjugate a promising light-harvesting system.
