Viologen capped by nucleobase—building blocks for functional materials: synthesis and structure–properties relationship

Abstract The current study presents a new class of functional derivatives ( 1–3 ) consisting dicationic viologen (4,4’-bipyridinium unit) V 2+ capped by nucleobases thymine NB 1 ), adenine 2 thymine/adenine , and ion-paired with amphiphilic anion 3,4,5-tris(dodecyloxy)benzene sulfonate DOBS − ). target our work focuses on the design synthesis molecular building blocks in which three different functionalities are combined: chromophore unit), recognition thermotropic liquid crystal unit). resulted materials exhibit crystalline properties at ambient temperature significant particularities-induced mesogen structure. Structure–properties relationship providing knowledge about (1) how thermotropic, redox properties, thermochromism, or ionic conductive influenced presence purinic pyrimidinic nucleobases, (2) effective is their ability to self-assembly hydrogen bonding nonpolar solvents. has been proved have substantial impact electron transfer rate during reduction moieties intermolecular aggregation. Ionic conductivity thermochromic were investigated compared non-containing nucleobase analog methyl MV) as reference. Graphical abstract
