Themed collection Trends and Challenges in Porphyrinoid Chemistry

Studies on carbaporphyrins and other macrocycles preserving a fundamental porphyrin framework that confines a metal centre in the proximity of a carbon fragment enforcing a plethora of interactions and reactivities are reviewed.

The first milestone of advancing from multistep to one-pot syntheses, allowed for systematic investigation of corrole/metallocorrole properties and the design of new derivatives for their introduction as the key elements in advanced applications.

Subporphyrinoids constitute a class of extremely versatile and attractive compounds. Herein, a comprehensive review of the most recent advances in the fundamentals and applications of these cone-shaped aromatic macrocycles is presented.

This review summarises advances in chemistry of tetrapyrrole sandwiches with rare earth elements and highlights the current state of their use in single-molecule magnetism, organic field-effect transistors, conducting materials and nonlinear optics.

This review summarizes the chemistry of nonplanar porphyrins in terms of synthetic strategy, structural features governing their properties, unique functionalities derived from ring distortion, and further development of related research.

This review summarizes the recent advances in light driven catalytic H₂ evolution and CO₂ reduction systems towards the production of solar fuels, utilizing porphyrin or phthalocyanine derivatives.

This Review summarises the history and the ‘state-of-the-art’ development of lanthanide (Ln) porphyrinoids as theranostic agents. Applications such as near-infrared (NIR) fluorescence imaging (FL), magnetic resonance imaging (MRI), radiotherapy, chemotherapy and phototheranostics will be discussed.

The diverse coordination modes and electronic features of actinide complexes of porphyrins and related oligopyrrolic systems (referred to as “porpyrinoids”) have been the subject of interest since the 1960s.

Methyl-coenzyme M reductase (MCR) containing F430 as a nickel hydrocorphinoid cofactor is responsible for anaerobic methane generation and oxidation. This review describes the fundamental function and recent protein-based functional models of MCR.

The review summarizes the exploitations of corrole derivatives in many different fields, where the peculiar properties of these contracted macrocycles lead to the development of promising applications.

Recently, Baird (anti)aromaticity has been referred to as a description of excited-state (anti)aromaticity.

The review focuses on the synthesis, structure, aromaticity, and electronic and coordination properties of inverted and fused expanded heteroporphyrins.
