new type of molecularrods consisting of two (or more) rigid units linked by a flexible joint. Consequently we called these constructs articulated rods (ARs). The syntheses of ARs were carried out by a flexible and modular approach providing access to a number of compounds with various
functionalizations in terminal positions. First applications were presented with pyrene, cinnamoyl and anthracenyl labelled ARs.

One of the basic principles in living nature is based on shape-persistent and
mechanical parts: rods, joints, sleeves, plates etc., but with nanoscopic scale. Amongst these building blocks, molecularrods attracted particular attention in the last past decades [1][2][3][4][5][6]. Molecularrods, i.e., conformational rigid molecules in which the length considerably exceeds width and
