Recent developments in meta-benziporphodimethene: A new porphyrin analogue
Abstract
The article underscores a unique class of benziporphyrin analogues, in which two of its meso-carbon atoms are sp3 hybridized, leading to the formation of a new molecule: meta-benziporphodimethene (meta-BPDM). This molecule exhibits intriguing structural, spectroscopic and chemical properties. meta-benziporphodimethene was first discovered 16 years ago. Although, initially it was an accidental product obtained while synthesizing meta- and para- benziporphyrin, but the molecule stood-out when acted as a chemo-sensor for Zn2+ ions. The discussion here, starts with outlining the importance of porphyrin molecules, followed by the progress in the field of its synthetic modifications. Special emphasis has been given to the new porphyrin analogue: meta-BPDM. We have herein covered some recent applications reported like metal-ion sensing, breast cancer detector, UV- turn-on behavior for toxic metals of meta-BPDM. Owing to its low synthetic yield, not much research has been done on these systems, despite their beneficial properties. We have also inculcated the factors that may lead to enhancement of product yield of meta-benziporphodimethene systems. The X-ray and NMR analysis indicating weak agostic interactions has also been discussed. This article shall provide a better understanding of this class of carbaporphyrinoid family, to its readers and may open new paths for exploring these systems in future.
