B,N-doped PAHs from tridentate 'Defects' - a bottom-up convergent approach for π-extended systems.

A logical construction of monomeric subunits armed with the carbonyl functionality allowing post-synthetic reactivity leads to the convergent formation of π-extended defected units activated with BBr. The kinetic or thermodynamic control entraps either the pyrido[2,3-]quinoline or the 4,7-phenanthroline motifs doped with boron(III), which deeply modulates the optical properties.

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

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.
