trefoil-shaped poly(THF) both having an alkyne group at the core position (II and III, respectively) have been introduced as versatile core-clickable kyklo-telechelic precursors. The prepolymer II has been prepared by an ESA-CF (electrostaticself-assembly and covalentfixation) process using an assembly (1a/2b), composed of two units of linear poly(THF) having N-phenylpyrrolidinium saltgroups carrying

each containing a 1,5-dioxynaphthalenering. In its reduced state the ring-in-ring recognition motif, between the meta and para bisradical dicationic cyclophanes (rings) defines the [2]rotaxane, whereas in the oxidized state, the cyclobis(paraquat-4,4'-biphenylene) cyclophane encircles the two 1,5-dioxynaphthalenerings in the bifurcated 'tail'. The redox-controlled molecularshuttling, which can be likened

Synthesis of some novel stilbenoid dendrimers with the phenothiazine surface group has been achieved using Horner–Wadsworth–Emmons (HWE) and click reactions through convergent methodology. Alkyl chains have been incorporated at the periphery of phenothiazine moiety to enhance the solubility of the dendrimers. The photophysical properties indicate an increase in the molar extinction coefficient, fluorescence
