This article reviews recent developments that have taken place in research related to new porphyrin architectures and their host-guest chemistry, as described in a microsymposium bearing the same name held during the 3rd International Conference on Porphyrins and Phthalocyanines (ICPP-3). The usefulness of representative arrays, aggregates, donor-acceptor systems, and receptor motifs based on porphyrin architectures is highlighted as it applies to the fabrication of molecular devices, understanding the biomimetic electron transfer processes, and recognition of bioorganic substrates.
