series of rigid π-conjugated mono-, bis-, tris-, and tetrakis(terpyridine)s 3–8 was synthesized in high yields by means of Horner–Wadsworth–Emmons (HWE) reactions between benzyl phosphonates 1 and an aldehyde-functionalized terpyridine derivative 2. The photophysicalproperties of the materials in solution and in the solid state depend strongly both on the numbers of terpyridine moieties attached to the

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

An o-phenylenevinylene-bridged tetrapyrrolicmacrocycle (2) was synthesized by means of a Horner-Wadsworth-Emmons reaction between benzylbisphosphonate and SEM-protected diformylpyrrole, followed by deprotection of the SEM groups. This conformationally flexible tetrapyrrole can be considered as an expanded calix[4]pyrrole analogue, which acts as a receptor for the chloride and bromide anions in THF-d8
