Dyes and photoluminescent compounds based on polymethine dyes that contain at least one alkyl-phosphonate or substituted alkyl-phosphonate group, including the synthetic precursors, methods of synthesis, and applications thereof. Certain embodiments include heterocyclic ring systems and polymethine linkage are selected such that the resulting polymethine dye is a cyanine dye, a merocyanine dye, or a styryl dye.

In the pocket: The supramolecular interactions between a Rh phosphine catalyst equipped with an anion‐binding pocket and alkenes that contain anionic functionalities (see picture) provide an excellent design concept to achieve remote control of the regioselectivity in hydroformylation reactions. The 4‐pentenoate and 3‐butenylphosphonate, which fit tightly between the Rh center and the pocket, were
