BODIPY- and Porphyrin-Based Sensors for Recognition of Amino Acids and Their Derivatives

Abstract

Molecular recognition is a specific non-covalent and frequently reversible interaction between two or more systems based on synthetically predefined character of the receptor. This phenomenon has been extensively studied over past few decades, being of particular interest to researchers due to its widespread occurrence in biological systems. In fact, a straightforward inspiration by biological systems present in living matter and based on, e.g., hydrogen bonding is easily noticeable in construction of molecular probes. A separate aspect also incorporated into the molecular recognition relies on the direct interaction between host and guest with a covalent bonding. To date, various artificial systems exhibiting molecular recognition and based on both types of interactions have been reported. Owing to their rich optoelectronic properties, chromophores constitute a broad and powerful class of receptors for a diverse range of substrates. This review focuses on BODIPY and porphyrin chromophores as probes for molecular recognition and chiral discrimination of amino acids and their derivatives.

Sn(IV) Porphyrin-Based Ionic Self-Assembled Nanostructures and Their Application in Visible Light Photo-Degradation of Malachite Green

“…These nanomaterials display unique features, including large surface areas and high physicochemical stability, compared to their parent compounds. Highly ordered and versatile geometric features render these materials suitable for applications in other fields, including chemical sensing [18], molecular recognition [19], catalysis [20], solar energy conversion and storage [21], and biomedical purposes [22]. Porphyrin molecules aggregate in solution and self-assemble to form larger stable molecules.…”

Synthesis and photophysical properties of novel oxadiazole substituted BODIPY fluorophores

“…[26][27][28][29][30] In addition, a number of BODIPY derivatives have been conjugated as energy donors with porphyrin or metalloporphyrin acceptors. [31][32][33][34] The core structure of BODIPY can usually be accessed in two priority one-pot approaches. 35 Syntheses of symmetrical BODIPY dyes include sequential acid-catalyzed condensation of diverse a-unsubstituted pyrroles with aldehydes, oxidation and BF 2 complexation using BF 3 ÁOEt 2 under basic conditions.…”

Broadband Visible Light-Absorbing [70]Fullerene-BODIPY-Triphenylamine Triad: Synthesis and Application as Heavy Atom-Free Organic Triplet Photosensitizer for Photooxidation

“…Herein, we designed and synthesized a broadband visible light-absorbing [70]fullerene-BODIPY-triphenylamine triad ( C 70 -B-T ) as a heavy atom-free organic triplet photosensitizer for photooxidation. BODIPY, owing to its high chemical stability, simple synthetic route and adjustable π-conjugation framework [ 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ], was selected as the light-harvesting antenna in this triad. As we know, the absorption wavelength of unsubstituted BODIPY is at ~500 nm and the absorption range is relatively narrow.…”
